How CURT uses USCAR

CURT uses the standardized USCAR 7-way socket to provide a complete line of custom tow wiring solutions. CURT USCAR compliant connectors bridge the connection between the USCAR socket on the vehicle and the standard plug on the trailer.

We offer 7-way RV blade connectors, 4-way flat connectors, dual-output connectors and more.

Simply plug the USCAR connector into the vehicle socket, and your vehicle is ready to accept a trailer wiring plug!

Other standardized connectors

While some vehicles don’t use the USCAR socket, they have a different standardized socket solution. Some Dodge vehicles and others use a rectangular, 8-prong configuration. To allow this socket to utilize CURT’s complete line of USCAR parts, we offer the wiring adapter #57300.

Vehicle manufacturers that use the Dodge socket:

  • Chrysler
  • Dodge
  • Freightliner
  • Jeep
  • Mitsubishi

What is an OE replacement connector?

Original equipment (OE) refers to the parts and equipment that originally come with a vehicle, straight from the vehicle manufacturer. An original equipment replacement connector is simply a wiring connector that plugs into the existing wiring on the vehicle.

CURT OE connectors are designed to replace or equip the vehicle with a standard wiring connection for towing a trailer, utilizing the factory USCAR or Dodge socket.

If the USCAR socket on your vehicle is damaged or in need of replacement, the CURT USCAR plug #56229 offers the solution. This replacement connector comes with blunt-cut wires and is designed to splice into the existing wiring, providing a standard USCAR socket to plug in a CURT OE replacement connector.
