A CURT connector provides a reliable connection for your trailer wiring, using an industry-standard format, such as a 4-way flat, 6-way round or 7-way RV blade. They can be used to install new wiring on a vehicle or trailer or as replacement connectors for existing wiring. This particular connector is a 7-way RV blade socket and is designed to mount on the vehicle-side of the connection, to accept a trailer wiring plug. It features a USCAR base to connect to a standard USCAR plug, found on specific Ford, GM and Nissan vehicles. Once plugged into the USCAR socket, it provides a connection for the taillights, turn signals, brake lights, backup or reverse lights, electric trailer brakes and a 12-Volt battery. It also provides a connection for the ground wire. This trailer wiring connector is built to withstand the elements. It is constructed from durable black molded plastic to be impervious to rust, and it features a dust cap with a spring mechanism to keep out rain, salt, grime and dirt when the connector is not in use.

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 RV blade connector is designed to plug into a USCAR socket and supply power for tail lights, turn signals, electric trailer brakes, a 12-volt battery, reverse lights and brake lights, as well as a ground connection. It is intended to be a replacement trailer connector, plugging into a standard USCAR socket (see application info to verify fitment with your vehicle). It features rust-free black plastic construction and comes with a spring-loaded cover to keep out dust and water. This 7-way RV blade connector is a female-end socket, specifically designed for the vehicle side of the connection.

⭐ Strong and reliable, but a bit bulky
Size: 18" Blue
Pros: Heavy-duty feel, doesn’t slip, fits most lug nuts Cons: Larger size makes storage tricky Experience: Used this during a tire change on my SUV. The grip gave me good leverage and felt secure, though I wish it folded for easier trunk storage. Who It’s For: Drivers who want a sturdy emergency tool. Verdict: 4 stars — dependable, gets the job done.
