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. To complete this custom wiring connector, it comes with a rubber dust cover. This cover keeps the connection points clean and well protected when the connector is not in use.
