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 a special license plate light hole socket that mounts in any 1-1/4 license plate light hole for a convenient attachment point. It is constructed with durable molded rubber and is made with 36 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.
