Edit: I found the thread
Hey lagwagon, I think there is an old thread with a step by step on installing fog lights. I can confirm that installing them in a pre-facelift bumper is a 10 to 20 minute job. You will need new black fog light bezels, fog lights, factory relays, fuses, and the mirror control switch with the fog light button. When I installed mine I ordered the bezels and fog lights new and went to a scrapyard for the relays and switch. The car is pre-wired so it's all plug and play.
