MK5 Headlight Harness (12 Pin to 10 Pin Hardwire Conversion)
This harness is designed for vehicles equipped with factory 12 pin Bi Xenon headlight wiring converting to aftermarket or halogen style headlights using a 10 pin connector.
Unlike the other headlight conversion harnesses, this version requires a hardwire installation. An OEM 12 pin female connector is not available for this application, so the harness uses individually labeled wires and crimp connections to adapt the factory 12 pin wiring to the 10 pin headlight configuration.
Key Features

Important
This is a hardwire conversion harness and is not plug and play.
Installation requires cutting the existing 12 pin headlight wiring and connecting the individually labeled wires using the supplied crimp connections.
Basic automotive electrical and crimping experience is recommended for installation.
Please confirm that your vehicle has the factory 12 pin Bi Xenon headlight wiring and that your replacement headlights use the 10 pin connector before ordering.
If you are unsure about compatibility, send your VIN along with photos of the factory and replacement headlight connectors and compatibility can be confirmed before ordering.
Why This Harness?
A suitable OEM 12 pin female connector is not available to produce a conventional plug and play adapter for this conversion.
This harness provides a properly labeled hardwire solution for adapting the factory 12 pin Bi Xenon wiring to a 10 pin headlight configuration without replacing the complete vehicle headlight wiring loom.
