I added fog lamps to my base roadster last year. I was fairly simple to do. I got both fog lamps on ebay used for a lot less than new ones at the dealership. You do have to run wiring from the back of the switch to the lamp itself. You can go to
http://homepage.mac.com/gregmeach/XFire/ and go to the lighting section to see exactly what terminals on the back of the switch you have to hook up for the power to the fog lights. Also, you need to insert the proper fuse into the side of the switch. It turns on by pulling the **** one time.
If you need any other help, PM me!
