2003 Yukon Denali Brake Controller Installation

Published 06/03/2015

Question:

Is there an easy plug in system for an electric brake controller in my 2003 yukon denali? Ive been told it plugs in under the dash, but went to do that and there is no plug the same as what the parts store gave me. Another person told me if it has the seven prong plug in the back that i dont need one. I am not sure I was given the correct one from parts store but I tried two different ones. Any suggestions?

If you have the factory 7-way at the rear of your 2003 GMC Yukon (sounds like you do), all you would need to install a brake controller like the part # 90885 would be the correct install harness, # 3015-P.

It will plug into the black junction box under the dash of your vehicle. I attached an install video and a help article for you to check out as well. There will be a few connections under the hood of your vehicle that you will need to make as well.
