Wire Harness

The wire harness is connected to the trailer’s electrical system using a trailer-side connector. The connector is usually located at the rear of the trailer and is designed to plug into the towing vehicle’s vehicle-side connector. The vehicle-side connector is usually located near the hitch and is connected to the vehicle’s electrical system.

When selecting a wire harness for a boat trailer, it is important to choose one that is compatible with the towing vehicle’s electrical system. The harness should be rated for the maximum amperage of the trailer’s electrical system to ensure that it can handle the load. It is also important to choose a harness that is long enough to reach from the trailer’s connector to the vehicle’s connector.
