How to Wire a Battery for a Trailer Break Away Kit
Towing a trailer can be hazardous, especially if the trailer becomes detached from the tow vehicle. Installing a trailer breakaway kit can mitigate such incidents. A breakaway kit triggers a switch that activates the trailer's brakes if a breakaway occurs. To effect a breakaway kit, your trailer needs a battery. If it doesn't already have one, you will need to install a battery to power the breaker without the vehicle's electrical connection.
