Vehicle-side connector that plugs directly into your factory USCAR socket, equipping your tow vehicle with both a 4-way flat and 7-way RV blade output in a single unit.
There's nothing better than a component that plugs in perfectly without any cutting or splicing, and that's exactly what the Curt 57015 delivers. Just snap it into your existing factory USCAR socket, and your tow vehicle is equipped with not one but two standard outputs: a 4-way flat and a 7-way RV blade, ready to connect to most trailer wiring systems.
This connector supplies power for tail lights, turn signals, electric trailer brakes, a 12-volt battery feed, reverse lights, and brake lights, plus a dedicated ground connection. It's constructed from durable, rust-free black plastic and comes with a rubber gasket and spring-loaded dust covers on both outputs to keep the connections dry and protected when not in use.

This connector requires a factory tow package with a USCAR-style socket already installed on your vehicle — it's a direct OEM replacement connector, not a new wiring installation. Confirm your vehicle has a compatible USCAR socket before ordering.
In The Package: • One (1) Dual-Output 7-Way/4-Way Connector
