Fogs on with headlights off? 91 GT - 5/6/2004 12:12:46 AM    2CLN4U   Posts: 22 Joined: 3/19/2004 Status: offline I have a 91 GT and it has fog lights. The problem is they only turn on when I have the headlights on. I want to be able to have them (fogs) on by themselves or with the parking lights on, or maybe also with the brights on. I tried testing some of the wires behind the headlight switch but was unable to find the right combination to make it work. Does anyone know how to do this correctly?

I know the switch is different. I guess they could possibly be wired the same. _____________________________ 88 GT W/t-tops, deleted smog pump, AC and power steering. Mac Headers, O.R.

All you need to do is have the parking lights supply power to the switch so when activated it can energize the relay making the fogs come on. By having the parking lights supply power you will have it both ways, headlights off fogs on, headlights on fogs on. _____________________________ www.storminstangsofconnecticut.com (in reply to 2CLN4U) Post #: 6
