I put Xenon lights in the high beam and fog lights of a Navi and thought there might be some interest:
To start out with the high beams, remove the three screws that hold in the headlight cluster. The 3rd is a little hidden in the first pic, but is shown in the second:
Remove the 3 harness plugs going to the headlight assembly.
Once you have the headlight out, put it on something soft, remove the rubber dust cover, pull the plug off the factory bulb, and it will look just like this:
Make a 15/16" hole in the rubber boot to accept the kits grommet like so:
Attach the HID kit plug to the factory plug inside the housing:
Insert bulb into high beam socket and turn. It only goes one way. Here is a comparison between the halogen and Xenon bulbs:
Insert wires into the housing and replace rubber boot. Now to find a place to mount the ballast. There is a perfect, flat place to mount it:
I used acetone to clean up the back of the ballast and the area it is to be attached to, and then used the insanely sticky double sided pad that comes with the kit. Theres no way its coming off!
Attach the ballast wires to the wires coming out of the rubber boot, tidy up the wiring, and reinstall headlight using 3 screws. No different for the other side.
The foglights are simple as you don't have to remove anything. Just remove the factory bulb, unhook it from its plug, and plug in the Xenon kit the same way as with the high beams. You wont be using the grommet as there is no dust cover for the foglights. Secure the excess wires with the zip ties that come with the kit:
Note, that with the foglights, at least on my Navi, the polarity was reversed. The plugs can be turned around 180 degrees, but then they can't clip. My solution worked fine, though you may come up with something better:
Here is a comparision between the stock foglight on the left (passenger side) and the 5000K Xenon on the right (driver side):
I shopped around and decided to go with GT HID. I can get these for any members for $100 shipped per kit (kit = two lights) for any car. PM me if you're interested. I looked and there are no HID vendors on this site, so hopefully I'm not stepping on toes. If I am, you can delete this and keep the writeup and pics.
If you have any questions, feel free to ask!
