HID headlights

this kit (i guess most of em) was completely plug and play
i had to drill a 1 inch hole through the plastic cap at the back of the head lights, to run the wiring through
the plug that normally goes to the bulb now goes to the wiring harness, through the grommet and out the cap
then it connects to the ballast, and two other wires come out of that (through the grommet into the cap) plug those two wires into the new bulb and that it

(you do want to drill a few holes to mount the ballast somewhere, but thats peanuts)

think it took me about 20 minutes and that was because some brilliant engineer decided the best place for the coolant overflow reservoir was right in front of the passenger side headlight)
