White Ground Wire Is Taped To Orange Wire 2009 GMC Sierra 1500 Brake Controller Install
Question:
2009 GMC Sierra 1500. I see 3 wires to connect to but the white ground wire is tied in to some other wire. Should I run a ground directly to the negative terminal of the battery with a 10 ga wire?

Helpful Expert Reply:
You want to use the white wire in your photo for the ground. The other orange wire is the CHMSL circuit which stands for center high mount stop light wire. It is not used by a brake controller so you can tape it up and stow it out of the way. You will need 4 wires to install the brake controller, 12 volt power (red and black in your photo), trailer brake output (solid blue in your photo), stoplight circuit (light blue with stripe in your photo) and ground (white).
