Wiring Trailer Breakaway

By | July 23, 2022



A trailer’s breakaway system is a vital safety feature. It helps to prevent catastrophic damage or serious injury should the trailer come loose from the tow vehicle. What’s more, it’s often required by law. Understanding how to wire a trailer breakaway system will help you stay safe and in compliance with laws in your area.

Installing a trailer brakeaway system isn’t too difficult. However, it does require attention to detail and the correct materials. You’ll need a breakaway switch, a 7-way plug and receptacle, the breakaway kit’s battery, and several electrical connectors. It also helps to have access to some basic tools for any necessary wire splicing or crimping.

The first step is to mount the breakaway switch and connect its leads to the battery terminals, using the included battery cable. Then, the switch’s lead must be connected to the trailer’s brake connector. In most cases, this will involve running a wire from the switch to the 7-way receptacle in the trailer, then connecting the brake connector lead to the blue wire in the 7-way plug. If there’s no blue wire in the plug, a wire should be spliced into the corresponding connector on the trailer itself. Finally, the battery must be tested and the trailer brake connector checked to make sure it’s properly calibrated. With this complete, your trailer is now equipped with a breakaway system, ready to ensure your safety while on the road.
