Trailer Breakaway Controller Wiring Diagram

Trailer Breakaway Controllers are essential components of any trailer safety system. They act as a back-up to the primary source of braking power in case of an emergency. Without a functioning breakaway controller, your trailer may not be able to stop quickly enough if the primary source of braking power fails, putting you and your passengers at risk. Understanding how to properly connect and wire your trailer breakaway controller is essential for ensuring safe operation.

A trailer breakaway controller consists of a battery, a switch, and a manual brake lever. The battery is used to provide power to the switch, which is then connected to the trailer brakes. When the trailer disconnects from the tow vehicle, a spring-loaded pin connecting the switch and the brakes is released, activating the manual brake lever. This lever is then used to apply the brakes manually, bringing the trailer to a stop.

Wiring your trailer breakaway controller correctly is essential for ensuring proper operation. There are two main steps involved in wiring a trailer breakaway controller: connecting the battery and wiring the switch. When connecting the battery, first attach the positive (+) cable to the positive terminal on the battery, and then attach the negative (-) cable to the negative terminal. Then, connect the switch to the positive (+) terminal on the battery, followed by the manual brake lever, and finally the trailer brakes. Finally, ensure that the switch is in the off position before connecting it to the trailer brakes.

Following these steps will ensure that your trailer breakaway controller is wired correctly and ready to provide an additional layer of safety to your trailer. Always check your trailer’s wiring before each trip to ensure that everything is secure and in good working order.
