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 connector features a vehicle-specific design to perfectly fit certain years of the Toyota Highlander (factory tow package required). It uses an OEM-compatible connector to plug into the vehicle’s OEM socket 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.
