How-To: Kensun HID Conversion Kit InstallationPosted: November 26, 2011
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.
