To install a brake controller in a 2015 Toyota Tacoma all you need is the correct install harness. But first you will want to pick out a brake controller.

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.

For an install harness you would then need the # 3040-P.
