I used a Tekonsha Prodigy P3, it's the wired version.



You just need power and ground for the brake controller (you can easily get power from the front +12v terminal in the engine bay, make sure you use a resetting breaker) and then run a wire back to the trailer loom. I don't remember, it was a while ago, but I think you have to run the wire all the way to the 7-pin connector. Everything else should be taken care of IIRC as long as you have the towing module, which connects the rest of the wires in the 7-pin connector.
