Hi all, i am hooking up a brake controller to my 2005 Dodge Ram, 1500, 2 wheel drive, quad cab, 4.7. I used the generic diagram that came with the controller to find my cold/switched wire from the brake switch.According to the manual my wire should be white/tan, however, it seems that is constant power because it reads 24 volts at the trailer connector always. I know that i can put pins in each of the wires and depress the brake pedal and check the wires, but im getting old and my back hurts when im tucked under the steering wheel
. Does anyone know what wire i should be using,or can someone point me to a diagram online. By the way, there are approx 6 wires in the harness.
