I am trying to install an Even Brake supplemental braking system to tow my Equinox behind a motorhome. Installing a Roadmaster part # 88400 Brake-lite relay and need to find the cold wire to hook up the relay. There are three wires at the brake switch. Can anyone tell me what color wire is the "Cold" wire? Thanks in advance.

none of them....use the white wire at the BCM in the black plug pin 11

I know this is an old post but you may still be able to help. I want to tow our 2013 equinox and was wondering how you accessed the wiring to install the brake relay. It looks almost impossible. Did you remove panels under the dash to get to the brake switch? Also how did you get wires from the engine compartment into the cabin?
