How to Install a Brake Controller in a 2008 GMC Envoy
Published 04/09/2015 >
Question:
Can you send me a wiring diagram for the DrawTitie Activator IV as far as installing it on a 2008 GMC Envoy? I had it on a Trail Blazer and need to switch it to my new car but my mechanic needs to know how to connect the electric.

Expert Reply:
To install a brake controller in your 2008 GMC Envoy there are 4 blunt cut wires under the dash that the controller will wire to using butt connectors.
Have your mechanic check out the link I attached that details everything needed to install a brake controller in your vehicle. I also attached an install video.
