Additional Information

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 slicing 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 CURT electrical converter is 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. It is designed to fit certain years of the Audi Q5 (except hybrid), BMW 328i xDrive sedan, BMW X5 SUV, Infiniti M37x sedan or Mercedes SLK250 (to verify your vehicle compatibility, see the CURT application guide at

This converter is 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. Plus, to give you peace of mind for the long haul, the majority of CURT converters are proudly made right here in the USA.
