Product Description

CURT 56405 custom wiring harness provides a convenient way to add a 4-way flat trailer wiring connection to compatible Volkswagen vehicles. The vehicle-specific T-connector design plugs into the existing factory taillight wiring, helping minimize cutting, splicing, and modification of the vehicle’s original wiring.

The 4-way flat connector supplies the basic trailer lighting functions needed for tail lights, brake lights and left/right turn signals. The harness incorporates a powered converter to help protect the vehicle’s electrical system while providing power to the trailer lights.
