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 7-way USCAR replacement harness is designed to replace an existing USCAR plug and supply power for tail lights, turn signals, electric trailer brakes, a battery, reverse lights, and brake lights, as well as a ground connection. It features rust-free black plastic construction and comes with color-coded wires and 24" of bonded wire for easy splicing into your vehicle's wiring system. This 7-way USCAR connector is a female-end socket, specifically designed for the vehicle side of the connection.
