OEM brake controller
Hello DN looking to see if anybody knows how to activate the OEM brake controller on this 2020 Sierra . Truck didn't come with it so customer bought it at dealer and installed.

Any help would be greatly appreciated.

I think you have 2 options: Call ACDelco support for access to a special calibration. or install an aftermarket controller.
