CURT 7-Way RV Blade Socket 55415 — USCAR Replacement, Plug-and-Play with Spring-Loaded Dust Cover

The CURT 55415 is a direct-replacement 7-way RV blade female socket made to plug into a USCAR vehicle outlet, restoring trailer lights, brakes, reverse and auxiliary power with a dust-covered, rust-free housing.

If your vehicle’s factory USCAR outlet needs a fresh, reliable connection for towing, the CURT 55415 gives you a purpose-built, no-splice replacement. Designed to work with common Ford, GM and Nissan USCAR sockets, this female-end 7-pin RV blade connector supplies power for tail, turn and brake lights, electric trailer brakes, reverse lamps and a 12-volt auxiliary feed. The housing is molded from black plastic to resist corrosion, and a spring-loaded cover helps keep moisture and debris out when the connector is not in use.

How does this CURT socket restore trailer electrical functions?

Install the 55415 by plugging it into your vehicle’s USCAR receptacle to re-establish a full 7-circuit connection. It routes ground plus the six standard trailer circuits so your trailer’s lighting, braking and auxiliary systems receive power exactly as intended.

• Complete 7-way wiring: tail, brake, turn, reverse, electric brake, 12V auxiliary and ground
• Female-end socket designed for the vehicle side of the harness
• Fits standard USCAR sockets used on many Ford, GM and Nissan models

What makes installation straightforward for most users?

This CURT replacement socket is engineered to be plug-and-play with a matching USCAR outlet — no cutting, splicing or complex rewiring required when your vehicle already has the USCAR port. That reduces install time and the chance of wiring mistakes, so you can get back to towing quickly.

• No cutting or splicing when mating to a factory USCAR socket
• Simple push-fit installation that aligns with OEM wiring pins
• Compact shape and spring-loaded cover for easy daily use

How durable and weather-resistant is the CURT 55415?

The socket housing is made from black plastic that won’t rust or corrode like metal alternatives, and the integrated spring-loaded dust cover helps keep the contact faces clean and dry. Together these features extend service life and maintain consistent electrical contact under typical road conditions.

• Rust-free molded plastic housing resists corrosion
• Spring-loaded cover seals out dust and moisture when unused
• Robust construction suitable for regular towing environments

Will this fit my vehicle and trailer wiring?

This part is specifically built to mate with USCAR-style vehicle sockets; confirm your vehicle’s connector type before ordering. If your vehicle has a factory USCAR outlet, the CURT 55415 provides a standard RV blade 7-pin interface for any trailer wired to that industry standard.

• Designed for vehicles equipped with a USCAR socket (common on many Ford, GM, Nissan models)
• Provides a standard 7-pin RV blade interface for trailers
• Check vehicle fitment details to ensure compatibility
