Brake Controller Recommendation for 2002 GMC Sierra with Aftermarket 7-Way

Question:

I have 2002 GMC Sierra SLE 1500 4WD Z71. I had a shop wire in a 7 pin plug in preparation for purchasing a trailer with brakes. They went off the factory distribution block by the spare tire. Im looking to purchase a brake controller but all of the look like they require factory 7 way plug and my truck did not have that. What brake controller can I use?

First let's start with 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.

Next, for a wiring kit to install the brake controller to the 7-way you would want the Wiring Kit for 2 and 4 Brake Electric Brake Controllers # 5506. 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.
