2018 GMC Acadia brake controller install
Just finished a brake controller install on my 2018 Acadia with tow package. Wire for the controller were at the firewall just around the gas pedal area. Fairly easy to do, with basic tools like a line tester, tape, butt splices, and zip ties. Thanks to GMC for making this a DIY job. Check out the photos of the finished product, sorry about the pic orientation.
