Like trailer hitches and ball mounts, electrical connectors range all over the board in shape, size and capability, but no matter what your trailer's electrical functions are, you need a solid connection to keep the power flowing and ensure safety on the road. CURT electrical connectors are designed and manufactured to give you a reliable connection every time you plug in your trailer. This 4-way flat connector is designed to supply power for tail lights, turn signals and brake lights, as well as a ground connection. It features durable rubber-molded construction and is made with standard color-coded, bonded wire. It also includes snap locks, a mounting bracket and all necessary installation hardware to easily splice into your vehicle's wiring system and mount on the rear of your vehicle. This 4-way flat connector is a female-end socket, specifically designed for the vehicle side of the connection. It is compatible with all 2-wire vehicle systems.
