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 a special license plate light hole socket that mounts in any 1-1/4in. license plate light hole for a convenient attachment point. It is constructed with durable molded rubber and is made with 36in. of standard color-coded, bonded wire to easily splice into your vehicle's wiring system. This 4-way flat connector is a female-end socket, specifically designed for the car side of the connection. It is compatible with all 2-wire vehicle systems.
