4 WAY PLUG W/SPRING

This is a 4-way male plug with a spring strain relief, commonly used on the tractor side of a tractor-trailer electrical connection. It transfers power for trailer lighting functions (tail, turn, and brake lights) from the truck to the trailer via four wires secured by internal set screws. An external clamp screw holds the wire bundle in place, and the spring protects the cable from damage at the plug entry. When replacing this plug, it's important to photograph the existing wire positions to ensure correct reconnection and proper light operation.
