Brake Controller Port Location on a 2014 GMC Sierra 1500  


where is the plug in on my 2014 gmc sierra for a brake controller. i know its under the dash but i cant find it.

Its in the junction box located under the dash, to the left of the steering column just above the carpeting. The recommended harness to install a Tekonsha brake controller is the Tekonsha Plug-In Wiring Adapter # 3016.

I attached an install video for this harness that shows how it would install.

The brake controller we recommend the most is the Prodigy P2 Brake Controller part # 90885. This is the best selling controller on the market because of how easy it is to setup and use, and how well it works. This controller is designed to work with the # 3016.
