John, I bought my fog lights at a discount dealer for $200 and installed them in 2 hours at home. The lights bolt right in, a plug is located on the fender to plug into the lights. The interior switch is easy, you just pull out the blank and the fog light wire is attached to the blank. Plug that in to your new switch. The hardest part didn't take too long, that is to plug a new relay into the relay box under the dash. I had to do this by feel, since I couldn't see where I was reaching to under the dash. Good luck, MH
