2015 GMC 2500 Sierra Brake Controller and Install Harness Recommendation

Expert Reply:

Your 2015 GMC Sierra 2500 came pre-wired for a brake controller. All you would need is the correct install harness for the truck. If you went with a Tekonsha brake controller like our best selling P2 part # 90885 all you would need is the install harness part # 3016.

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.
