Truck is a 2004 GMC Sierra...

Is there a way to make the fog lights default to ON? Like the ASR/ TCS in the F cars can be defaulted to off. I like the fog lights, but can never remember to turn them on and hate having to keep turning them on everytime I start the truck.

 

TTT... maybe?

 

i know it has been done i have read it some where. just can't remember where. i actually think there is a kit made to do it. i will do some looking and see if i can find out where i saw it.

 

when i put my own PIAA foglights and airdam on, i was able to get it to turn on with the truck's ignition. i hooked up the positive lead to the stereo with a wire tap/splice. you might be able to do the same thing. i would get a light tester to find hot wires to the stereo, then tap the foglight wires to that.

 

There is a company that sells a relay kit for this purpose, or Keuka's suggestion. Sorry but I cannot remember the name the copany right now.
They also sell relays that keep the foglights and low beams on when you engage the high beams.
