When your vehicle does not readily provide an electrical connection for hooking up your trailer, CURT electrical converts offer the solution. Working tail lights on your trailer are absolutely essential any time you tow, and a converter provides an effective way to properly equip your vehicle for safe towing. A CURT electrical converter, much like our custom vehicle-to-trailer wiring harnesses, provides a trailer connector on your vehicle by splicing into the vehicle's electrical system. Electrical converters are designed to splice directly into the taillight wiring, rather than plugging into various sockets, giving them the nickname "taillight converters". Though it requires a little extra work compared to a custom wiring harness, a tail light converter offers a reliable, long-term connector solution. This package contains 30 converters. These CURT electrical converters are designed to convert a 3-wire system to a 2-wire system and provides a standard 4-way flat connector socket to plug in your trailer. They fit certain models of Acura, Audi, Buick, Chevrolet, Chrysler, Dodge, Eagle, Ford, Geo, Honda, Hyundai, Infiniti, Isuzu, Kia, Mazda, Mercedes, Mercury, Mitsubishi, Nissan, Oldsmobile, Peugeot, Plymouth, Pontiac, Saturn, Suzuki, Toyota, Volkswagen and Volvo (to verify your vehicle compatibility, see the CURT application guide at curtmfg.com). These converters are made with cutting-edge surface-mount technology (SMT) circuitry, featuring electrical components that are mounted directly to the surface of the board rather than being inserted into a series of holes. SMT circuits have longer life cycles, lower resistance, reduced heat generation and are more reliable than through-hole-mounted components.
