Kurt,

That would be wonderful. I can wait til Saturday because the new switch will not be here until friday. I tested the wires in the picture and the pink/black wire is the only one that is hot (when the head lights are on). Also the wire that I said was white is really white with a blue stripe (missed the stripe on the back side). I'll be looking for where this system was modified today and Thursday. Thanks again for your help.

The four wires to the switch are correct and working. In my previous post I said that the only wire that was hot was the pink/black wire. Actually the white and blue stripe wire is hot too (bad cnnection on testing). This wire actually also connects to the rear window defrost switch too as per 328 wiring diagram. So I have 2 hot and 2 ground. I will begin to trace back to find the modification.

 

I hooked the wires to one of the other switches (they looked the same). This is what happened: Fog lights now work on low beam. You turn on the headlights, press down on the fog light switch and the fog lights come on along with the indicator light on the dash. This seems correct. (Thanks for the offer Kurt, but I figured out where the wires go on the switch). However, I wasn't able to determine why the fog lights come on with the high beams regardless if the fog light switch is on or off. Also if I just have the parking lights on and then also depress the fog light switch I only get the parking lights. No fog lights. It sound like some people get both the parking lights and fog lights on together when both switches are pressed? Not sure where to look next. Checked behind fuse panel at the head lights etc. Ideas?
