Brake Controller Recommendation and Install for 2004 Chevy Avalanche 1500
Updated 09/22/2018 | Published 09/21/2018
Question:
I just bought a 2004 chevy avalanche. It does not have a trailer brake conroller installed. It has a round 7 pin connector installed by the hitch. By reading the owners manual it sounds as it is wired for trailer brakes. How can I tell if the wiring is installed because if it is installed then I belive I just need to buy a controller. Thanks,

Your 2004 Chevy Avalanche that has a factory 7-way at the rear of the vehicle is factory pre-wired for a brake controller but you will need a quick-install connector part # 3015-P to connect to the port of the junction box under the dash of your truck.
For a brake controller I would recommend the Prodigy P3 Brake Controller part # 90195. 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. This will be the last brake controller you buy. It can easily be transferred to future vehicles as well.
I attached an install video that shows this process on a similar Avalanche as yours with a Curt brake controller. It's the same process though.
