My 98gxe didn't have any pre-wiring for the fogs. And i didn't feel like spending 100+ for the harness. So i made one out of 'ford mini clips," some wire, a relay and heat shrink tubing from pep boys. Wired the relay to the driving lights.
The fogs lights were kinda a bitch to install. I had to take apart the *WHOLE* front off to get them on. Some members here have squeezed the fog brackets on without taking off the front, but i wanted to go the safe way. Took me about 3 hours. But if you don't take the front off, i'm sure it would take no more than 30 minutes.
