If your trailer breaks away from your tow vehicle, your brakes won't work unless they have power. This kit adds a battery and switch to keep the brakes working, and it's required by law on most trailers with EOH disc brakes.
You're wiring a trailer with electric brakes and safety isn't optional. This breakaway kit gives the trailer with a backup plan. If it comes loose, the battery triggers the brakes. It's got everything you need to stay in control.
