Plug-and-play replacement connector that plugs directly into your vehicle's factory USCAR socket, restoring a full 7-way RV blade trailer connection with no cutting or splicing required.
The Curt 55415 is a replacement 7-way RV blade connector designed to plug directly into your vehicle's factory USCAR socket. It supplies power for tail lights, turn signals, electric trailer brakes, a 12-volt battery feed, reverse lights, brake lights, and a dedicated ground connection — everything a 7-way trailer connection needs to function.
Because it plugs into your existing factory wiring, there's no cutting or splicing required for installation. It's built from rust-free black plastic and includes a spring-loaded dust cover to keep water and debris out of the connector when it isn't in use. This part fits select Ford, GM, and Nissan vehicles already equipped with a compatible USCAR socket.
