Wow Schmoo, you're right about them making it too easy, you can just plug the ballast right into the stock socket!! I've got some Lexus IS300 HID's in my car and they were one of the easier installs when I put them in. The ballast tied right into the stock socket wires, but I still had to cut the stock socket off. I didn't do a retrofit or anything and mine are working fine. Decent cut off line and they don't blind anybody. I installed them July of 2004 so it's been over a year and they're working fine. My camera sucks at night shots.
