7 Pin Trailer Wiring With Brakes. Trailer Wiring and Brake Control Wiring. Anyone have a diagram of which pins supply which functions?
Information and Flyers - Ron's Toy Shop (Luella Willis) Trailer plug wiring is standardized across all vehicles, no point trying to find vehicle specific info. You can also control the trailer brakes with a little lever on the front of the controller. Something to be said for the wires being in a wiring harness.
I'm considering adding brakes to it.
Just wire the appropriate wires to the ones described above and then wire the ground to a good ground at the frame.

It is on the "cold" side with voltage only when the pedal is pushed. All makes and models are designed differently, so you'll need to have a service or repair. Worried about RV brake controller warnings?
