Brake Controller Wiring Harness for a P3 and 2015 GMC Sierra 1500
Published 12/16/2014 >
Question:
Will this harness fit a 2015 GMC Sierra with the heavy duty trailering package but not with integrated factory brake controller. I saw the video for a 2014 and I think they are the same but wanted to make sure.

Yes, the brake controller wiring harness # 3016 will fit your 2015 GMC Sierra 1500. You do not have to have the factory integrated brake controller option in order to use the harness.
For a brake controller the P3, # 90195, is one of the most popular brake controllers available. It has a lot of customizable features, diagnostics, not to mention it is a reliable and well-made controller. I have linked that video you mentioned. Installation will be basically identical on your truck.
