These harnesses provide a true plug-and-play solution for upgrading to MK7.5 European-spec tail lights. Installation requires no pinning or de-pinning, and the harness uses 8-pin blue connectors for a perfect fit and OEM-level reliability when properly installed and coded.
 
Features
Plug-and-play installation, no wiring modifications or repinning
Uses 8-pin blue connectors tailored for MK7.5 European-spec tail lights
Built with OEM connectors and automotive-grade wire
Designed for clean integration and long-term reliability
 
Keyway Modification
Some factory connectors on MK7.5 models have a keyway tab that prevents the blue connectors from seating fully. If this occurs, the keyway on the factory female connector must be carefully shaved off. This minor adjustment allows proper fitment without affecting connector integrity.

Once properly installed and coded using VCDS or OBD11, the harness functions seamlessly without triggering fault codes. It fully replicates OEM light behavior for smooth, reliable performance.
 
Coding Required
Full functionality requires coding to enable all light channels. Detailed instructions are provided in the PDF guide below.
