This harness provides a standalone fog light solution for MK4, MK5, and MK6 Golf and Jetta models. It does not integrate into the BCM and instead operates as an independent circuit, making it ideal for vehicles that did not come pre-wired for fog lights.
Installation requires routing and connecting wires to specific locations, but all components are pre-terminated for a clean, professional finish.
