If there has been a post on this, I apologize for asking about it again. I did a quick search and didn't see anything on it, but I'm sure there is. My question is simple; is there a way to get the Fog Lights to turn on without having to turn the Head Lights on? Thanks as always for the help guys.

You can if you rewire the lights between the lights and the switch. Otherwise, I don't think anyone has figured it out that I know of. There was someone here who used the factory wiring to put in his own after market fog lights. He mentioned something about leaving out the relay and the fog lights are always on, or are on when the parking lights are on. I'll have to search through a few threads to find that one.

This thread shows the wiring schematic for the fog lights. According to this, the fog lights should be coming on when the tail lights are on. But that is not the case. Maybe it can be rewired at junction A38, if we can find out where that is.

Thanks for the quick reply Tox. I wasn't sure if this was a common interest or not. At a minimum, I would like the fog lights to come on when the parking lights are on, not just when the headlights are on.

I know mhadden was trying to do the same thing you are trying to do. Maybe he will chime in and let us know if he has found or done anything to help.
