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 Super Duty, F350 Super Duty, F450 Super Duty, and F550 Super Duty. 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. 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.
