It plugs into the vehicle's 4-flat socket to carry the trailer's lighting signals—tail lights, brake lights, left and right turn signals, and a ground. It's the most common connector style for small utility, boat, and light-duty trailers, and is typically replaced when the original plug becomes corroded, damaged, or the wires pull loose.
