Question:

I have 1995 K2500 Chevy. I am trying to add a brake controller for a trailer. I connected the trailer to another truck and the electric brakes work great. I cannot get the electric brake to work with my controller. I have tryed 3 different controllers. We have run the ground right from the battery to the plug. I suspect it has something to do on where I need to connect the red wire for the brake signal. Any help would be appreciated.

The wire from the cold side of the brake switch is what you are looking for. This wire is white, bundled next to an orange wire, under the dash, located above the brake pedal. Using a circuit tester, like part # PTW2993, make sure you have the wire that only has voltage when the brake pedal is pressed.

I would also recommend you check the rest of the connections on your brake controller. Make sure you have 12v going in on the black wire, 12v exiting on the blue wire, and make sure your white wire is properly grounded.
