On some versions of the 2016 GMC Savana with the 7-Way tow package the blue output brake wire is already ran from the back to the front. It is located under the dash near the emergency brake pedal.

Some models will require a wiring kit to run wire to the battery. This may require drilling a hole in the firewall to run the wire. You may use kit 5506 which includes 20, 30, and 40 amp breakers.

This will provide the power source and ground for the wiring for the brake controller. You will need to test the wires from the brake pedal switch of your vehicle to find a circuit that has voltage when the brakes are applied and none when not applied. This will be the circuit you will run the red wire to.

Finally you will need to run a length of 10 gauge wire (part # 10-1-1) from the brake output circuit of the controller to the brake output circuit of the 7-way (blue wire). The # 10-1-1 is sold by the foot so you will need to order a quantity of the amount of feet you will need.

For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes.
