MK5 Headlight Harness (10 Pin to 12 Pin Conversion)

This harness is designed for MK5 / PQ35 vehicles originally equipped with factory 10 pin halogen headlights converting to OEM 12 pin Bi Xenon headlights.

The factory halogen and Bi Xenon headlights use different connector and wiring configurations. This harness adapts the factory 10 pin vehicle wiring to the OEM 12 pin Bi Xenon headlight connection without cutting or splicing the original wiring.

A built in capacitor stabilizes the PWM lighting signal to prevent main beam flickering when operating the Bi Xenon headlights.

Key Features

• Converts the factory 10 pin halogen headlight connector to an OEM 12 pin Bi Xenon headlight connector • Built in capacitor stabilizes the PWM signal and prevents main beam flickering • Supports low beam, high beam, DRL, and marker light functions where applicable • Plug and play design with no cutting or splicing required • Uses OEM style connectors and the correct automotive wire gauges • Properly sized and sleeved for clean factory style routing

Fitment & Compatibility

• MK5 / PQ35 vehicles originally equipped with factory 10 pin halogen headlights • OEM Bi Xenon headlights using the compatible 12 pin connector configuration

Not Compatible With

• Aftermarket headlights using a different connector or wiring configuration • Adaptive or other non standard headlight configurations

Important

This harness does not support automatic headlight leveling or adaptive headlight functions.

Please confirm that your vehicle has the factory 10 pin halogen headlight connector and that your replacement headlights use the OEM 12 pin Bi Xenon 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?

MK5 vehicles equipped with factory halogen headlights use a 10 pin wiring configuration that does not directly connect to OEM 12 pin Bi Xenon headlights.

This harness adapts the required lighting circuits to the 12 pin Bi Xenon configuration while the integrated capacitor stabilizes the PWM signal for proper main beam operation, all while keeping the original vehicle wiring intact.
