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 5-way flat connector is designed to supply power for tail lights, turn signals, reverse lights and brake lights, as well as a ground connection. It features durable rubber-molded construction and is made with 48\" of standard color-coded, bonded wire to easily splice into your trailer's wiring system. This 5-way flat connector is a male-end plug, specifically designed for the trailer side of the connection. 5-way flat connectors are commonly used on boat trailers with surge brakes.
