<p>A custom trailer hitch wiring harness 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.</p> <p>This custom wiring harness features a vehicle-specific design to perfectly fit your model vehicle. 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.</p> <p>To complete this custom wiring harness, it comes with a rubber dust cover. This cover keeps the connection points clean and well protected when the connector is not in use.</p> <p><strong><span style="color: #ff0000;">WARNING:</span></strong> Cancer and Reproductive Harm.
