Splice-in vehicle-side socket for 7-way RV blade trailer connections. Integrated mounting bracket, spring-loaded dust cover, concealed terminals. Rust-free black plastic. Wires not included.
The Curt 58417 is a vehicle-side 7-way RV blade connector socket designed to splice into your existing vehicle wiring and provide a reliable connection point for a trailer plug. It handles the full range of trailer electrical functions — tail lights, brake lights, reverse lights, turn signals, electric trailer brakes, auxiliary 12-volt power, and ground — making it a complete solution for towing RV travel trailers and other 7-way blade-equipped trailers.
Built from rust-free black plastic, the 58417 features concealed wire terminals that protect splice connections from dirt, moisture, and corrosion. A spring-loaded dust cover keeps the connector face clean when no trailer is plugged in. The integrated mounting bracket makes installation straightforward, securing the socket directly to the vehicle frame or trailer hitch without additional hardware.
