If a vehicle is not equipped with factory-installed trailer wiring, CURT offers two options: custom wiring or a taillight converter.
Within custom wiring, there are two more options: custom wiring harnesses and custom wiring connectors. A custom wiring harness uses multiple vehicle-specific plugs and connects to the vehicle’s electrical system through the taillights. On the other hand, a custom wiring connector uses only one vehicle-specific plug.
Despite their basic installation differences, custom wiring harnesses and custom wiring connectors are fairly similar. Both feature an easy, plug-and-play design, and both typically provide a standard 4-way flat output. If custom wiring is not available for a particular vehicle application, a taillight converter may be required.
