CURT custom wiring is the best option for equipping your vehicle with a trailer wiring connector. It offers a vehicle-specific solution with no need for cutting, splicing or soldering. However, if custom wiring is not available for your specific vehicle, CURT offers the taillight converter -- a universal trailer wiring option. This CURT taillight converter provides a standard 4-way flat connection for hooking up your trailer lights to your vehicle. It features highly durable construction, able to withstand harsh elements, road salt and vibrations. The converter is built with a potted enclosure in which the electrical components are encased in a solid compound that seals them off from moisture and impacts. Even when mounted outside, underneath the vehicle, it provides long-lasting dependability. This taillight converter is compatible with a wide variety of vehicles, including models from Dodge, Ford, GM, Honda, Kia, Mazda, Nissan, Subaru, Toyota, Volkswagen, Volvo and many others (to verify your vehicle compatibility, see the CURT application guide at curtmfg.com). The converter is designed to convert a 3-wire vehicle system to function with a 2-wire trailer system. The converter features color-coded wires and a wiring guide for easier installation, and it comes with snap locks for a secure connection (a powered taillight converter wiring kit, such as the CURT #55151, is also required for installation). Most CURT taillight converters are constructed with surface-mount technology or SMT. This type of circuitry features smaller electrical components that mount directly to the face of the circuit board, resulting in reduced heat generation, enhanced performance under vibration conditions, maximum light intensity and maximum operating life. CURT converters are also fully tested, both optically and load-tested, to ensure reliable performance.
