Wiring for Electric Trailer Brakes

13646 Views 9 Replies 5 Participants Last post by  BoneHead

Have a 1998 Suburban 1500 that I am wiring for electric trailer brakes. Have everything in but the wire that goes to the brake switch - can't get my old, fat hand up high enough to grab it. Since there is only one bulb (or set of wires that go to the brake light I can't run it to there. Does anyone have a tip or trick on where to connect the brake signal wire to? The vehicle does not have a heavy duty towing package - at least not that I can find. All it had was the four connector at the rear. For enticement some home made chipotle :great: chile powder for the right answer.

thanks - NMTROUT

I've been meaning to do this for awhile...

This is what I used on my truck (99 K2500 Sub) On the left kick panel distribution block is a spot marked "NAT", just above the relays. The right terminal is the cold side of the brake and the left terminal is the parking light circuit. USE YOUR TESTER TO BE SURE.

Put your test light on the right terminal and push the brake pedal - if it lights, you're in business!

Good luck,
Nice setup
