Question:
I need to install a brake controller and 7 way plug on 99 yukon SLT 4x4 which has a tow package. It has a pre-installed 4 flat plug on the rear near the receiver. Is it pre-wired for a controller or do i need to run all the wiring, find the cold side of my brakes, etc

Helpful Expert Reply:
Your 1999 GMC Yukon is not pre-wired for a brake controller so to install one like our easy to use and reliable Brake EVN # TK63VR on your SUV that has a 4-way currently would require the 7-way/brake controller install kit part # ETBC7 which comes with everything needed to convert to a 7-way as well as wire in the brake controller.
I attached an install video for this on a similar 1999 GMC Suburban which will be basically the exact same as your Yukon.
