Identifying 5th Circuit of Trailer Wiring
Question:
I have a trailer wiring kit that has green, white, yellow, brown, and red. I need to add a 4 prong plug which has a yellow, brown, white, and green. I was wondering where to attach the red wire.

Expert Reply:
Red isn't a standard color for trailer wiring that uses 5 wires so you'd have to track down that circuit to determine what it controls and wire as needed. It's most likely a reverse light circuit for either a lock out solenoid wired to the back of a surge brake actuator or for reverse lights at the rear of the vehicle. For a 5-way connector with 25 feet of wiring we have the part # A25W5B.
