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. These CURT taillight converters provide a standard 4-way flat connection for hooking up your trailer lights to your vehicle. They feature highly durable construction, able to withstand harsh elements, road salt and vibrations. Each 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 package contains 30 converters. These taillight converters are 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). Each converter is designed to convert a 3-wire vehicle system to function with a 2-wire trailer system. They feature color-coded wires and a wiring guide for easier installation, and they come with snap locks for a secure connection (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.
