Fog Light Question, Running the fog lights to turn on with the parking lights Options

[str8thugginit4ya]

Hey guys,

I have the 96-99 fog lights already installed in my car. I was just wondering how can I run them to turn on when you just have the parking lights on? Right now, it only turns on when I put the headlights on. Oh, and I have the OEM light switch for the fog lights and I'm not thinking of running another aftermarket switch just for this.

One wire, one splice. Done. Your not bypassing the the relay, or doing anything to the switch. The switch sends 12v to the relay, the relay sends 12v to the fogs, fogs light up. ONLY thing that has changed is the fogs come on when you turn on the fog switch. The reason why is you changed to a 12v source with the ign. on, instead of it getting the 12v source that is available ONLY with low beam lights on.

Now that I recently had time to examine it, I understand you fully and appreciate the advice. By listening and feeling it click I know which relay powers the parking lights (one on one board) and which relay powers the fog lights (one on a different board). You can call me lazy - but I'd like to know by color code which wire it is that sends power from the parking light switch when it is turned on. If I can locate that and use the parking light feed instead of the headlight feed, that's the way I want to do the change. Taking both those under-dash panels down to locate the one correct wire is a real PITA, and short of that it's tough, as there must be at least a hundred wires there. I can pick probe the wires to verify the switched hot wire feed coming from the parking light switch. Does anyone have a wiring diagram that will tell which wire it is?

Oh, and it would also help to know which wire is the headlight switch feed that is currently powering that fog relay.
