OrangeCrush,
Thanks for taking the time to explain. My 2005 doesn't have any wiring harness on the left pillar. I was told by the GM parts guy that the H2 must be equiped with "USD option"...(don't know what that is) to hook the lights up. I like to install the lights but it appears to be too difficult because it doesn't come with necessary items to be a "plug & play". You might have to give us guys, especially me, who don't know much about electrical work on the "how to" step by step instruction. Did you also make your own switch? Delta light 10x would be nice but it has too many lights for my needs. The factory low-profile 4 lights would be perfect for what I need it for. Thanks again.
