ok so im trying to hook up a brake controller and I am at where i need to connect to the cold side of the stop light switch.
I am pretty sure I found the connector that is at the top of the brake pedal arm, but it has about 6 different wires on it.
does anyone know which wire it is or if im even looking at the right thing

 

On the question to the brake light switch. DON,T disconnect the brake light switch. It will not work when you reinstall it. I had to buy a new one. Once removed it can not be reinsalled. About the cold side of brake wire switch, I,m looking at the same problem. I,m thinking about running new wire an installing another brake light switch stright to the battry
