I have a '97 Blazer 4wd. I would like to wire a set of driving lights using a factory switch. Right now the spot for the switch has a blank, however when I had the dash bezel off, I noticed what looked like the factory wiring for the switch. There is also wiring and plugs at the front bumper where the lights would be. My question is, can I just get the factory switch and plug it into the wiring in place and go? Or am I hoping for too much?

 

dont know a whole lot about the factory wiring, but if it comes down to it you can wire them up with a relay, using a hot from the factory headlight switch as the switch for the relay, its really not that complicated if you have a test light or acces to the factory wiring diagrams

 

The problem is that most factory switches are momentary switches, meaning they do not latch on or off. To use one, you would need to setup a latching relay arrangement that would take that momentary pulse (when you press the button) and turn on and off the relay(s). the12volt.com has schematics for latching relay arrangements.

I would try to find a way to just put a toggle or latching push button in the factory location.

 

i wasnt refering to the factory fog light switch , but the actual main headlight switch. that is either on or off, it does not return back to original position when u turn them on, so it would work fine with a standard 4 or 5 post relay
