The wiring diagram with the kit I purchased leaves a lot to be desired. It looks like there are 4 wires coming out of the housing on the brake pedal. Which one is the correct one to connect the electric brake controller to? I’m planning to tow a trailer with electric brakes this weekend.
Easier said than done. There are four wires and they can’t be easily probed from under the dash. They are in a molded connector. Any other ideas?
