Brake Controller Wiring on a 1994 GMC Safari
Published 07/16/2008
Question:
I have a 1994 GMC Safari Van with the towing package. According to my Brake controller instructionsTekonsha there should be a 10 pin connector that the red wire is connected to. I dont have that connector. I connected Tekonsha tech dept and they had a bulletin on this model that corrects the instructions, they are looking for the bulletin that has the correction. Do you have any ideas? I found my 12 wire under the dash and my blue wire for the controller to the plug.

Expert Reply:
The best bet would be to locate the stoplight switch at the top of the brake pedal, and then locate the wires or wiring harness that comes from it. Using a circuit tester, like part # PTW2993, probe the wires until you find one that shows a signal only when the brake pedal is applied.
