Curt USCAR Custom Wiring Harnesses & Connectors

  • Fits USCAR -equipped vehicles with factory tow plugs
  • Replaces damaged or missing USCAR vehicle harnesses

URT original equipment replacement connectors provide a reliable, plug-and-play solution for replacing a USCAR harness or other factory-installed trailer wiring harness. Most of our OE harnesses are equipped with a USCAR plug on one end and a standard trailer wiring connector on the other, such as a 4-way flat or 7-way RV blade. We also offer a Dodge-specific model. With the original equipment connector installed, your vehicle is ready to accept the wiring connector of your trailer.

We also offer dual-output OE replacements. These connectors feature the same USCAR or other factory connector and provide two standard trailer wiring outputs. Models are also available with an integrated backup alarm for added safety.

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 an OE replacement connector.
