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 Toyota Sienna. 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. This custom wiring harness comes with a rubber dust cover. This cover keeps the connection points clean and well protected when the connector is not in use.
