Trailer Breakaway System Wiring Diagram Availability


The camper is plugged into the truck and the truck is on and the brakes are applied. When I pull out the campers safety brake connection the electrical brakes work. Now the electrical box where the truck plug in cable is connected to all the camper wires is open. The blue wire coming from the truck side is not connected to any other wires. I test the voltage between the blue and the whiteground I get 12-13 volts. I run 2 new wires from the blue and the white to the brake magnet wires and the brake does not work. what dont I understand?


Expert Reply:

It sounds like you are looking for how to wire up your trailer breakaway system to your trailer so that the brake controller in your truck will activate them. The easiest thing for me to have you do is check out the picture I attached that shows how the systems need to get wired up.

I also attached a help article on breakaway systems for you to check out as well.

In case you have a brake magnet problem I attached a help article on how to troubleshoot them as well.
