Flicker. Flicker. Pop. Crap! Let there be light, I think to myself as I flick the high-beam switch to shed some lumens on the situation. My turn-signals only work when they feel up to the task, my emergency flashers have given up the ghost a long time ago, and the high-beam switch needs three-fingered coercion to be pushed into the “on” position. In short, my left-hand combination switch is an embarrassment and needs replacing. However, I really am not up to spending $228 plus shipping and handling on a collection of space-age buttons. After all, that’s a third of the cash required for that Dainese leather jacket I’ve been lusting over, or a new rear tire, or almost the cash needed to procure a Power Commander on sale. I can think of a multitude of things to waste $228 on, a multifunction switch isn’t one of them.
I ride around in semi-darkness for about a week or so, before it finally gets on my nerves. The Beemer’s headlight throws what looks like the image of a ghost rider’s full-face helmet on the road before me. It’s starting to creep me out; never mind that I can’t see shit and had almost run over a steaming pile of fresh deer guts one evening. I wondered where the rest of it was…
It’s time to buy an H7, 12V, 55W bulb to replace the burnt out low-beam stocker. I look around online and am not happy to see that one of those bright, bluish-white HIDesque jobs costs around $30. Hell, that’s a pair of knee pucks, right there. How much are HID conversion kits anyway? I go look and find very good reviews on a company by the name of Kensun. Never heard of them, but for $55 + $9.95 S&H, I’m going to pull the trigger on a set of 8000K Xenon eyeballs with slim-fit aluminum ballasts.
Three days later, I almost trip over the box on my doorstep on the way out for a high-velocity pleasure cruise. Needless to say I didn’t go for a ride that day. It’s time to wrench. Yet, again. It’s really quite the tragedy. I now own two bikes (yes, I bought a dedicated race bike while I was on my hiatus), do twice the wrenching and ride half as much. Hand me a pit crew shirt. Hell!
It’s easier and less frustrating if you take the nose off the bike, although you could do this without bothering with the plastics. To remove the nose, you’ll have to take the following fasteners off of both sides and nothing more (unless you absolutely insist on it):
· Unplug headlight connectors
· Remove mirrors
· The two screws above the headlight assembly
· The two screws on the uppers, forward of the BMW roundel
· Top screw on tank trim panel
· Lower plastic rivet which secures the inner fairing cover to the tank trim panel
· The three top-most screws on the inner fairing panel
Carefully work all the interconnecting parts free, and then pull the nose forward until it comes free. Take the damned thing inside and get comfortable with a beer and some power tools. 😉
The OEM protective screw-on caps have to be modded to allow for the additional wires and plugs of the HID bulb’s wiring harness that connects the bulb to its ballast and the bike’s factory power plug. The best tool to use for the job is a step drill bit. The HID kit is pretty much plug and play.
1. Unscrew one of the protective caps and stick the thing in a vise.
2. Drill a hole in the center of the cap, just big enough to allow you to shove the biggest of the three connectors through. If the hole is too big, the HID bulb’s rubber grommet will be too loose to allow for an adequate seal against the elements; if it’s too small – you guessed it — the connector won’t fit.
3. Once you have drilled the correct size hole, smooth out the rough edges. I used my Dremel tool and one of the orange grinding stone bits for this.
4. Rinse, repeat for the remaining cap.
1. Unplug the power plug from the back of the bulb.
2. Gently push on the lower two retaining tabs and remove the stock bulb from its socket by lifting the bottom out first. Do NOT use a screwdriver to pry the tabs open, or you’ll spend 30 minutes bending them back into useful shape to get a tight fit later. Ask me how I know… This is important! The bulbs have to be fully seated and be tight. Any rattling around in there and you’ll burn one out in let’s say… two commutes. Again, I don’t wanna talk about it…
3. Unplug the spade connectors from their plug and set the bulb aside.
4. Take one of the HID bulbs out of its protective case by unscrewing the top and gently pulling the base off of the wiring harness. Be careful not to touch the bulb or its burn-out time later. For once, I didn’t learn that one the hard way. And no, it is not an old wives’ tale that fingerprints, debris and various other contaminants will create hot spots and shorten the lifespan of a bulb. It’s true. It’s true. HID bulbs have a very thin wire running along the outside from their tips to their bases. Don’t mess with that either.
5. Route the harness through the modded stock cap and seat the grommet into that (hopefully correctly sized) hole which you’ve drilled a little while ago.
6. Install the HID bulb in the headlight socket. The little tab goes into the upper retention tab first, then push the bottom into the lower two retention tabs. The bulb should seat properly and should be in there tightly and flush against the socket.
7. Plug the spade connectors into the power plug. I don’t think polarity matters, but to be on the safe side, I plugged the blue wire into the slot which was previously occupied by the yellow wire marked with a white line.
The rule of thumb with same colored wires is that the one with the markings is usually hot (+) and the other ground (-). But what do I know? I’m a girl who’s scared of lightning.
8. Find a suitable place for the power plug inside the headlight housing. Pull any excess wiring through the rubber grommet, you should have the excess on the OUTSIDE of the socket, with just enough slack to avoid chafing or stress on the wires.
9. Screw the modded cap back on.
10. Rinse, repeat. You’ve got one more to do.
1. Get your hands on some industrial strength Velcro and stick some to the back of each of the aluminum ballasts. I prefer the loop side on the bike, in this case. Do as you wish, but please clean both surfaces first with some 50/50 alcohol-water mix or any other suitable chemistry. The Velcro won’t stick for long if you don’t. If your shit falls off at a buck-fitty-plus, you have nobody but yourself to blame.
2. Decide how you are going to route the wires and determine the placement of the ballasts. Clean the spot, peel the backing off of the Velcro and stick it to it.
3. Plug in all three connectors. They are all keyed, so no worries about which end goes with what.
4. Rinse, repeat. One more side to hook up.
· Take the nose back outside and reinstall on bike. If you have fasteners left over, and followed the optional step above to booze it up while you work, you’ll have to stop here and continue after you sleep it off. Otherwise, read on.
· If you have fasteners left over and you didn’t follow the optional step above to booze it up, I dunno what to tell you other than I hope it doesn’t fall off at an inopportune moment. Please continue…
I should have told you this earlier, but if you had read the installation instructions that came with the kit, you would not be in this predicament right now. I know, I know. It’s downright un-American to read instructions, manuals, traffic signs, or indicate a lane change by using proper signaling via actuation of the blinkers.
· Replace the 7.5A fuses in positions 4 and 5 with 20A fuses.
Yes, I had to run to the auto parts store to hook myself up. Half-blind and 15 minutes before closing time, Miss Busa could be found squidding it up the road with her Hello Kitty Pirate wallet shoved down the back of her pants, an iPhone snug as a bug in her bra and not a stitch of gear on her other than the legally required lid. ATGATT no more! As luck would have it, I had one 20A fuse, so I just unplugged the stock headlight connector on the high-beam side and went to the store. Glad I did, too. The two dudes working there followed me out the store and drooled all over my baby while I was putting in the newly acquired 20A fuse and reconnected the high-beam connector.
· Wipe drool from bike once you get home.
I would say, go for a test ride, but if you’re like me, you already did. Only one thing left to do:
· Adjust the headlights according to the instructions in the owner’s manual (or the ripped off BMW service manual I know y’all have downloaded) and be prepared to be illuminated!
Tying Up Loose Ends:
After you’ve made sure everything is working properly, route the wires to your liking, secure with cable ties and seal the rubber grommets with a suitable substance. I used Clear RTV Silicone Adhesive & Sealant. I should have used the black stuff.
Review to follow… after I’ve put some miles on these puppies.
…we’re not going to have a good time.
I don’t know what it is about safety wiring, but the task seems overwhelming and insurmountable and a big pain in the backside when you think about it; not to mention it is confusing when you first are faced with a list of stuff to secure properly to pass Tech at a track. I’ve been procrastinating this safety wiring project for the better of six months and I finally decided to tackle the subject in small increments.
Let’s start off with the important stuff:
The Tools of the Trade
- Safety wire pliers: This is a specialty tool that is technically not necessary, since you could clip the wire to size with wire cutters and twist the stuff with a pair of needle nose pliers. Technically. Do yourself a favor and buy one of these puppies! You’ll thank me later. No, seriously! Miss Busa is making these mandatory!
- Safety wire: The thickest wire I am using is 0.041″ T-304 stainless steel marine-grade lock wire, which is a perfect match for those 1/16″ drill bits. However, I use various thicknesses for different applications. I also use 0.032″-diameter and 0.02″-diameter wire. The skinnier the wire, the easier it is to work with, but due to its lesser tensile strength, it’s more likely to break. I like to use the thick stuff for places that have to be wired and are very unlikely to have to be undone. A medium-thickness wire is a pretty good all-around choice and I use it for most of everything that needs to be wired up. The skinny wire is great for wiring up such things as grips and rearset components.
- Racing safety pins: Completely optional, but they make life at the track so much easier. I like to use these in places where the wiring has to be undone and redone quite often, such as the oil fill cap, the radiator cap, the oil filter, the rear axle nut. Pay attention to the rulebook though, you may not be able to use these in certain places; the oil drain plug would be a common exception to their allowed use.
- Tab washers aka safety wire washers: Also completely optional, but these make things much more enjoyable. Also keep some of these in your tool box, you’ll never know when some extra-anal white-gloved tech inspector wants you to secure this or that and now you’re hard pressed to fix the problem since your drill is at home, no anchor point is within reach and your day could have just went down the tubes if it weren’t for these little lifesavers. 🙂 I like to use them where points of attachments are difficult or too distant to be feasible. You use them like a washer, torque the fastener down onto them, then use pliers to bend the tabs up around the bolt’s head. You can then secure your safety wire to the tab that has the hole in it. Obviously, you cannot use them as anchor points for safety wiring the exact same bolt you are attaching them to. That would be silly.
- Safety wire drilling jig: This is another specialty tool and a must-have item if you do not have a drill press and have to manually drill the holes into the bolt heads. Miss Busa is making this a mandatory purchase as well! No whining. Just order the jig set when you order the pliers and the safety wire.
- QUALITY 1/16″ drill bits. I mean it. Buy junk and they’ll break or won’t get you all the way through to the other side before they turn dull and useless! I’ve bought some DeWalt 1/16″ Split Point Cobalt drill bits which are claimed to have “maximum life in metal” and are rumored to “start on contact”. I can attest to both of these statements being fairly accurate so far.
- Automatic (spring-loaded) punch: Mine was broken, so I had to make do without; which isn’t a big deal IF you bought the aforementioned QUALITY drill bits. Tell me you didn’t buy junk! This is an optional item, unless you didn’t listen and bought a ten-pack of “titanium nitrate” bits for $1.98, then it becomes mandatory. This tool is used to make a little indentation for your drill bit to sit in to get you started and to help prevent the bit walking all over the place while you attempt to do so.
- Drill: I have some housewife-grade cheapie by Black & Decker. Variable speed, quick-release chuck, reversible. It does me just fine with those DeWalt drill bits.
- Vise: You either have to have one of these or try and talk your buddy into holding the piece for you while you come at them with the drill. 😉 I use a little suction cup mounted articulated hobby vise I got at Harbor Freight. I have no garage or workshop, so this little guy is prefect for the occasional Tool Time session.
- If you’ve got the cash to burn and the workshop to go with it, you might want to forgo the whole vise-and-drill thing and go out and get yourself a decent drill press. Way more accurate and way quicker, but overkill if all you’ll be needing it for is drilling a few holes into bolt heads to stick some wire through. Have a friend who has one? Pack your crap, hop on your bike and go see him. Don’t forget the pizza and the beer.
- Cutting oil: If you’re trying to find “cutting oil” you’ll run yourself nutters. Some people use WD-40 to cool down their bits, others use machine oil, or multi-purpose 3-in-1 oil. You get the picture. You’ll need something to keep the drill bit from overheating and to ease its passage through some of the tougher stuff you’ll ever find yourself drilling holes through. If the bit gets too hot, it’ll break.
- Safety glasses: This goes without saying. A scratched eyeball hurts like hell and you can’t ride motorcycles when you’re half-blind. Put ’em on!
Let the Fun Commence
Today, I’m doing caps and calipers. Since I have a short attention span and find learning how to safety wire almost as coma-inducing as teaching myself suspension tuning, I can only handle this mess in short spurts. I already have my axles, oil filter, and oil drain plug done. I will have to write them up later. Fear not, as this comes together I will re-organize these posts and work them into a proper how-to. This is really just something to get you started, to give you time to gather up all the tools you’ll need and give you a general idea of what is coming. I will take the mystery out of this subject yet. Because this is one of these things: You’re totally lost when you see the list of junk in the rulebook you have to properly secure, some of it makes sense. Some of it is vaguely familiar and some of it has you drooling form the corner of the mouth, mumbling incoherently. “Oil gallery plugs” anybody? As luck would have it, those beyotches may be secured with RTV silicone; a girl can do that laying on her back in two minutes flat. 😉
- Always take the parts you need to drill off the bike. Before taking them off, a lot of people like to mark their fasteners when they are properly torqued, so they know where to drill the holes for the wire. Plan how you are going to wire up the fasteners that you are taking off. Remember that safety wiring has to tighten one bolt as another tries to come loose, so the tension should always be to the right of each fastener, which will route the twisted safety wire in an s-shape between them once two bolts are wired together. Plan on drilling your holes accordingly. Some people drill more than one set of holes for just that reason, but I bet those are the same peeps who also own one of those snazzy drill presses. (I will post pictures of every secured bolt on my bike when I’m done. A pic is worth a million words and a hundred google searches!)
- Secure the part in your vise. Make sure you don’t bend or break anything. Always wrap your part up in a shop towel or use soft vise pads to avoid damaging anything. That’s one reason I decided to thread the bolt into the drill jig, even though my vise has soft rubber-capped jaws. That’s not exactly how you’re supposed to use the thing, or is it?!?
- Mark your fastener with your automatic punch, if you have one.
- Put a drop of oil on the drill bit and on the bolt.
- Carefully start drilling, making sure that your drill bit stays put and doesn’t wander around. With the DeWalt bits I mentioned earlier this is not a problem, they stay put, even without a punch to mark the spot. Once you have the hole started, speed up the drill and add a little bit of pressure, not too much, though, if you bend the bit you’ll break it. Let the bit do the work for you. Be patient. You’ll see metal shavings piling up, I prefer to clean those out with cotton swabs, wipe the drill bit off and add some more oil, then I resume drilling. Each bolt took me about 5-6 minutes to drill. I didn’t break a single bit either. 🙂 Remember those “titanium” cheapies? Yeah, I tried those first. After 10 minutes of nothing much happening, I finally admitted defeat and changed to the DeWalt’s. A world of difference! The no-name bits are going to have to be re-dedicated to drilling holes into wood or styrofoam… they suck!
- I decided to drill straight through the bolt heads, using the first hole as a guide to start the second hole. I thought that this may be a mistake and would make me break a bit, but it worked like a dream. The holes are nice and clean and perfectly aligned, which will make wiring these up a cinch, no matter where they end up in relation to each other. And I did a way better job than the ex-BMW dealer did on my axle nut, if I dare say so myself.
- The caps were easy. I decided to drill the radiator cap from the back side, so in case the bit slipped I wouldn’t scratch up the “pretty side”. That was probably a mistake, since I had to use my Dremel to deburr the side the drill exited, which is probably going to cause it to rust. We shall see. If I had to do it over, I’d drill the holes front to back. I drilled both sides of the cap because I couldn’t remember which was the one I had decided to drill. Should have marked it, but thought I wouldn’t forget. I put the racing safety pin on the side that I’m betting on. We shall see if I didn’t drill that extra hole for nothing.
- The oil fill cap is plastic and was done in a few seconds. It took me longer to put the part in the vise. I decided to drill both sides, because the cap could end up at a number of different angles in relationship to the safety wire’s anchor point.
Miss Busa’s How-To:
Installing a Tether Kill Switch
2010 BMW S1000RR
RND: Research & Delirium
I’ve googled myself to death trying figure out what type of switch I needed for the S1000RR and how to hook it up. A tension headache, one 800mg Ibuprofen, and a nap later I was still pretty much clueless. What little information I could dig up was conflicting and not very useful. Heck with it, I can figure this thing out myself. The biggest pain was trying to ascertain whether the S1000RR utilized a “normally closed” or “normally open” switch for the engine kill. Blech. Apparently nobody knew. The one reference I found on a certain S1000RR forum turned out to be wrong. Not that I gave much credibility to the thread, since it sucked and was no help to the people who wanted to know and were wanting to install a tether kill on their Double-R. The more I googled the more confusing it became. I finally found a reference on Pingel’s website that paired the words “normally open” and “magneto ignition” and “normally closed” and “battery ignition”. Magneto? I didn’t really know what exactly that was, but I’ve heard the term before in reference to old junk. So “normally closed” is what I put my money on. Off to buy a switch. My bike was in the shop, so I couldn’t look at it and couldn’t recall the information needed from memory. I really liked the PMR setup. The kill switch housing replaced part of the brake master cylinder bracket and it came with optional switch options. An extra switch? Always good for likely future upgrades. But I couldn’t recall if the S1000RR had a Nissin setup or not, so I decided to err on the safe side and bought an MPS switch, which was only half of an inch wide and fit 7/8-inch bars. It later turned out that I didn’t have the ½ inch to spare to cram that sucker onto the bar. Damn. I should have gone with my initial instinct. Oh well. Anybody want to buy a brand new MPS switch? Hit me up. ☺
Pingel has decent looking switches up for grabs, however I definitely don’t have room for them on my clip-ons and the panel-mounted option just didn’t fit the bill for me. I wear one-piece leathers. I have nowhere really to clip the tether other than making a wristband which will also keep the lanyard out of my way. I stole the wrist strap idea from the Pingel site, so kudos to them. ☺) I didn’t want a setup that would reach across bike or body parts. The Pingel switches to me look more to be made for cruisers or Harleys, not that I would have had the room for the bar-mounted ones anyway. I really wanted something a little more subtle and sporty.
Those are the only three viable options that I came up with in my research. There are other choices out there, but I dismissed them for various — now forgotten — reasons. I’m sure some of them were due to looks, design, price, or workmanship. I’m picky when it comes to my bike. I get the best I can afford and I want the stuff to last. The Pingel switches probably would outlast my bike. 😉
Slapped On The Wrist!
Yes, I could have just bought Pingel’s ready-made one, but I wanted to save some money and it would be kind of cool to make my own. I had most of the stuff already lying around from various other projects. I went to Joann’s to get a parachute buckle. 1-inch wide red canvas strapping, black retro-reflective iron-on ribbon, a 1-inch metal D-ring, the purchased $2 buckle and a sewing machine did the trick. I opted for white thread to do a little “contrast stitching”, but I should have just used red because my sewing skill leaves room for improvement… lots of wide-open room.
My difficulty finding a tether kill switch and trying to figure out how to install it stems largely from a lack of sufficient knowledge of electrical circuits, switches, basic wiring, and how ignition systems work. I had to beef up on long-forgotten high school physics subjects and educate myself in the application of the fine art of soldering wire joints. Basic Electrical Wiring 101 with a little something thrown in about relays, switching and simple circuitry.
Armed with a multimeter, Torx screwdrivers in various sizes, a clipboard, pen and my BlackBerry I got up close and personal with the Pirate. I took the engine switch/mode selector control pod apart and had a peek inside to figure out which one of the wires is the one the tether kill switch gets spliced into. This should also confirm whether or not the S1000RR employs a “normally closed” or “normally open” circuit. I had read somewhere that a good way to distinguish one from the other is by the number of wires that come out of the engine stop switch: two wires means “normally closed” and three wires is a sign of a “normally open” switch. I took the thing apart. I was presented with five wires hanging out of a keyed plug and a small PCB sporting three push buttons. Five wires? Great. I should have known. Why was I even thinking this could be as easy as following the one coming out of the stop engine button to note its color for later reference? I looked at the circuit board closely. I could definitely make out the paths of the circuitry. The pins on the plug are numbered. I also saw tiny numbers printed on the PCB. That made things a lot easier. The keyed plug also helped with keeping the orientation of things aligned correctly. It was time to draw a wiring diagram. After having studied the thing for a while it dawned on me that there is a place left for an option. A very faint cutout line on the switch’s front housing, an indentation on the PCB for an additional button with all the necessary circuitry in place, and three open slots in the keyed harness plug. Noting that, the whole mess became a little less confusing. Four functions, namely: Mode, Engine Stop, Engine Run, and Engine Start; one common connection to them all; it adds up to five wires. This started to actually make sense.
The multimeter proved useless, since the probes are too thick to fit into the harness plug and the entire circuit board is encased in some sort of clear plastic — to weatherproof the whole affair, I’m sure. So I ran my findings by Mr. Slow, but he refused to get involved, claiming lack of knowledge on the subject. I mulled it over in my head off and on for a few hours and then ended up sleeping on it.
I need a method to test my findings nondestructively. I don’t want to cut into a $1500 wiring harness on a hunch. I need some way to connect the male end with the female plug in isolation to engage in a little simulated wire snipping. Test leads. I could make myself little test leads to jump the pins. The female end is easy, but the pins on the male side need insulation to keep them electrically isolated from each other. After scrounging around for supplies I come up empty, naturally. I had, not too long ago, relocated my “computer graveyard” from its home in a closet to the neighborhood dumpster. It never fails. Hang on to the shite for years, not finding use for a single thing and as soon as you throw the crap out to make room for new junk you end up needing something from the pile.
I didn’t know what those “test leads” were actually called, so googling the subject proved to be coma-inducing, but eventually I hit on the name of the thing and once you can name it, you can find it in 0.0289 seconds. They are called jumper wires. They are used in robotics and prototyping to easily and quickly connect header pins on breadboard setups. They’re cheaper to buy than to make unless you have the stuff already lying around. I still would just buy them… trying to get those little fragile crimp pins onto the stripped end of a teeny wire sucks! I scored a pack of 10 6” male-to-female ones for about $4.
A Kick in the CANBus
With five jumpers in five different colors I set out to validate my thoughts on the kill switch subject. I dismantle the control pod once more, this time it only takes me a few minutes. I pull the plug out of its socket and use my spiffy wiring diagram to jumper the pins. After double-checking my work, I turn the ignition on and the RR begins its initialization. The RPM needle executes its customary sweep through the entire range of the dial, all LCD segments are displayed at once and all LED lights come on and blink off. The DTC and ABS indicators remain lit and blinking, as is expected. After the POST is complete, I put the transmission into Neutral and push the Engine Start button, the bike comes to life. No faults are tripped. All is as it should be. I pull the black wire that connects Pin 4. The engine dies instantly, just like it would if you had put the kickstand down while in gear. Still, no faults are thrown. I turn the ignition off and back on and try to start the bike again. Nothing. That too, is as it should be. I reinsert the wire to Pin 4, start the bike and press the Mode Selector button repeatedly to scroll through the four DTC modes. Again, all functions as expected.
Just for giggles, I yank Pin 5’s jumper wire out and nothing happens, the Pirate keeps on idling sedately. Pin 5 is the other half of the engine stop switch circuitry. Pin 4 is the connection that is common to all of the functions. Pin 5 is the wire I would have cut with a shaky, clammy hand had I have been on the bomb squad, sweating bullets with three seconds left on the ticker. Aren’t you glad I’m not on the bomb squad? I am. I am also glad that I took my time with this one and did it right. On the Hayabusa I would have spliced a wrongly cut wire back together. On the Beemer, the fear of the almighty CANBus and its renowned bitchiness saved me from myself.
The Pirate Is A Dead
This is a walkthrough of installing the PMR Stealth Kill Switch Combo. If you have another bar-mounted switch the install should be fairly similar.
- Remove the two-part housing of the right-side control pod. There is a small Torx-7 screw on the bottom part of the control pod’s housing, use firm, steady pressure and a precision screwdriver to remove it. Pull the front of the housing down and towards the front of the bike, until the plastic hinge on top separates and the two halves are free of each other.
- Unplug the harness plug from the top portion of the housing and place it out of the way.
- Use a Torx-27 socket or screwdriver to remove the two bracket bolts that secure the front brake lever assembly. Hold the assembly with one hand while you switch out the OEM bracket with the PMR switch housing and use the supplied #5 Allen bolts to fasten it to the bar. Don’t torque the bolts down just yet you still need to be able to move the assembly around a little.
- Route the wires of the tether kill switch to your liking and determine where you are going to splice them into the OEM harness.
- Once the position of your splice has been determined, cut the rubber tubing that protects the wires from the elements and from chafing. I used hubby’s nail scissors from his grooming kit, which are extremely pointy and razor sharp (shhhhhh! Don’t tell Mr. Slow.) Be careful not to nick the wires’ insulation. Once separated, cut a horizontal slit into the sleeve. This makes it easier to pull it out of the way and will also accommodate the added thickness of the bundle due to the newly spliced-in wires.
- Pull, then push-roll the tubing out of the way to expose the wires where you will splice in your tether kill. Give yourself plenty of space to work here.
- Snip the black wire with the blue stripe. That’s the common. IMPORTANT: If the colors of your harness wires do not match mine, you’ll have to find the wire that is connected to Pin 4.
- Strip about ½” of insulation off the ends of the four wires.
- Slip heat shrink tubing over the wires before you twist them together. I used 3/32” diameter tubing for the v-joint and 1/8” diameter for the straight joint. This way you won’t have to bend any wires and they’ll lie nice and flat against the harness bundle. It doesn’t matter which of the wires get paired, as long as you make the circuit whole again.
- Twist the wires together then solder the connections.
- Position the heat shrink over your solder joints and use a heat gun to shrink them down. Be careful where you point that thing, you don’t want to melt any of the S1000RR’s tasty bits, such as your brake or throttle lines.
[Alternatively, you can use crimp-style butt connectors, solder or crimp in quick disconnects, or use gel-filled 2-wire IDC (Insulation Displacement Connectors) butt splices but they will make your harness bulky and unless you can hide them somewhere, extremely visible.]
- To test your work crank up your bike. If it doesn’t start recheck your connections. Pull the plug out of the tether kill switch and your bike should die. If it doesn’t, in my best guesstimation I can’t help but assume that you screwed up somewhere… big time. I’m washing my hands of that one right now. *nods then turns and walks off quickly* “Gotta go!”
- Carefully pull the protective sleeving back into place. You might have to slit it some more to accommodate the new wires without bunching.
- Use electrical tape to wrap the spliced area tightly. It’s best to do it at a 45-degree angle and keep the stuff taught as you wrap the bundle.
- Follow up with friction tape to keep the electrical tape in place and from gumming up the works first time it gets hot and dusty. I also secured the ends with smallish cable ties to prevent them from unraveling.
- Go for a test ride. Don’t skip this step, it is VERY important to the entire process. It bears repeating: Go for a damn ride!
My work here is done.
