Here is the wiring diagram. Since you don't need pin 4 (12v Black) or the center pin (Aux 12v) for all of the lights and brakes to work, they are sometime not connected. Also might be a fuse somewhere. In my case, the wires were just in the bundle not connected.


Getting there is half the fun - take your time and enjoy the scenery.

It would be fused, but where to look for that fuse, I wouldn't have a clue.

Most manufacturers leave the fuse or relay out so there isn't a 'hot' lead back there until it's needed.

Good diagram, but I've never seen "orange" used in any trailer wiring/plug. Every 7-wy diagram I can find refers to the center aux. post as purple, typically used for back-up lights.
