CURT 57101 is a dual-output connector with a 7-way RV blade socket, a 4-way flat socket and a built-in backup alarm. It plugs into a vehicle's factory USCAR socket and replaces the factory-equipped 7-way socket. It is sold by socket type, not by vehicle.
Nothing is cut or spliced. The 4-way flat output carries tail lights, brake lights and turn signals, and the 7-way RV blade adds reverse lights, electric brakes and auxiliary power. The backup alarm sounds when the vehicle is in reverse. A metal bracket, mounting hardware and connector dust covers are included.
