This harness converts your factory MK7 halogen taillight wiring to support the MK7.5 LED NAR taillights. It’s a plug-in ready solution that requires only minor connector keyway trimming and includes full wiring and coding instructions for proper LED operation.
Features
Complete conversion harness, includes all wires, connectors, and coding instructions
Enables full functionality of LED turn signals, brake lights, and reverse lights
Uses blue plug connectors for direct integration (requires minor keyway trimming)
Built with OEM-grade wiring and proper automotive connectors
Includes detailed coding instructions for VCDS / OBD11
Fitment
Designed for MK7 (North American spec) vehicles upgrading to MK7.5 LED NAR taillights
Not compatible with European taillights that use amber turn signals or non-NAR LED layouts
Requires trimming the factory female connector keyway for proper fitment of blue plugs
Why Use This Harness
The factory MK7 halogen wiring is not pin-compatible with the MK7.5 LED NAR layout. This harness bridges the wiring difference cleanly, allowing all LED functions to work as intended without cutting into your factory loom or triggering fault codes.
Notes
Coding is required for full LED functionality, instructions are included in the PDF
Carefully shave the factory connector keyway to allow the blue plugs to seat correctly
