Curt custom wiring provides everything you need to connect your vehicle's electrical system to a trailer. With plug-and-play connectors, a custom wiring harness easily integrates with your vehicle taillights to provide a standard trailer wiring connector, typically in the form of a 4-way flat. This custom wiring harness features a vehicle-specific design to perfectly fit certain years of the dodge ram 3500 (to verify vehicle compatibility, see the curt application guide). It uses OEM-compatible connectors to "T" into the vehicle's taillight assembly and provides a standard 4-way flat output to power the taillights, brake lights and turn signals on your trailer.
