WARNING: Cancer and Reproductive Harm -

Making memories doesn't start when you reach your destination; it starts at the very first mile of your journey. Wherever your road begins and wherever it takes you, Bring It® with the power of CURT.

CURT custom wiring provides everything you need to connect your vehicle's electrical system to a trailer. With a plug-and-play connector, a custom wiring connector easily integrates with your vehicle to provide a standard trailer wiring connector, typically in the form of a 4-way flat.

This custom wiring connector features a vehicle-specific design to perfectly fit certain years of the Ford F250, F350 and F450 Super Duty (to verify vehicle compatibility, see the CURT application guide or use the Vehicle Lookup). It uses an OEM-compatible connector to plug into the vehicle's OEM socket and provides a standard 7-way RV blade output to power the taillights, brake lights, turn signals, trailer brakes, auxiliary and other electrical functions on your trailer.

To complete this custom wiring connector, it comes with a spring-loaded dust cover. This cover keeps the connection points clean and well protected when the connector is not in use. Once installed, the connector can also be conveniently mounted on the vehicle's trailer hitch receiver tube, using a CURT Easy-Mount connector bracket. The bracket mounts onto the trailer hitch with no drilling required, and its powder-coated steel construction provides a solid attachment point for plugging in the trailer wiring.
