bschelle Posted July 1, 2021 Report Share Posted July 1, 2021 I am installing a trailer brake controller in my 2007 DTS. I need to attach a wire from the controller to the cold side of the pedal sensor. Anybody know which wire that is or do you have a schematic of the wiring to the sensor?

rockfangd Posted July 8, 2021 Report Share Posted July 8, 2021 Hmm. Did the instruction specify for your type of switch? I only ask this because with these newer brake pedal position sensors I have not wired anything to them. I can try and look up a diagram tomorrow. I would say very likely it is not prewired for a brake control output. May be for the lighting but that's it. So you ran a harness to the rear I assume?

bschelle Posted July 8, 2021 Author Report Share Posted July 8, 2021 Save your time. I learned that the sensor wont work and I will need to attach to the CHMSL to get a positive connection only when the brakes are applied. There is not any controller connections on the DTS.

rockfangd Posted July 8, 2021 Report Share Posted July 8, 2021 That's what I was leaning toward. Different signals between the brake controller and the position sensor. If you don't mind me asking, what are you looking to tow with brakes? Quote GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
