2010 Silverado 1500 aftermarket brake controller

[JKnapp84]

Dropped the wiring bundle under the dash. First thing I noticed was no white wire in the bundle. The white wire looked yellow. Got everything hooked up and brake controller appeared to work. Then out of no where the brake controller would engage the trailer brakes without even pressing the peddle. The travel trailer dealer claims there’s a problem with my wiring. We tried 2 different controllers and it keeps happening. What can I do to fix this. I can’t safely haul this travel trailer just relying on my trucks brakes.

Sensitive brake switch?

I adjusted the gain several times on the controller. It would even do it after I slid the toggle over. 

 

I adjusted the the ground wire. Connected it directly to the frame and it seemed to help.

I was thinking the trucks switch

Where’s that switch located on a 2010 1500?

Google it, picture and some info,and it reminded me,if you have trouble with cruise control kicking off,that's the culprit

The switch is at the top of the brake pedal. It has several circuits and one may be bad. I replaced mine because the cruise would not work and then several months later the traction control and stabilitrack would not work. Brakes and lights worked OK though. Five minute install time.

I will get that switch replaced and see if that’s the culprit. I’ll keep you posted. Thanks for the info
