Electric Brake Control Wiring Provisions

GMC Sierra / GMC Sierra Owners Manuals / Driving and Operating / Towing / Towing Equipment / Electric Brake Control Wiring Provisions

These wiring provisions are included with the vehicle as part of the trailer wiring package. These provisions are for an electric brake controller. The instrument panel contains blunt cut wires behind the steering column for the trailer brake controller. The harness contains the following wires:
• Dark Blue: Brake Signal to Trailer Connector
• Red/Black: Battery
• Light Blue/White: Brake Switch
• White: Ground

The harness should be installed by your dealer or a qualified service center.

If the vehicle is equipped with an Integrated Trailer Brake Control (ITBC) System, the blunt cuts exist, but are not connected further in the harness. If an aftermarket trailer brake controller is installed, the ITBC must be disconnected. Do not power both ITBC and aftermarket controllers to control the trailer brakes at the same time.
