MK7 Headlight Harness (10 Pin to 14 Pin Conversion)
 
This harness is designed for MK7 / MQB vehicles originally equipped with factory 10 pin halogen headlights converting to OEM 14 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 14 pin Bi Xenon headlight connection without cutting or splicing the original wiring.
 
Key Features
 
• Converts the factory 10 pin halogen headlight connector to an OEM 14 pin Bi Xenon headlight connector
• Supports low beam, high beam, DRL, turn signal, 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
• Coding instructions available
 
Fitment & Compatibility
 
• MK7 / MQB vehicles originally equipped with factory 10 pin halogen headlights
• OEM MK7 Bi Xenon headlights using the compatible 14 pin connector configuration
 
Not Compatible With
 
• MK7.5 facelift LED headlights
• Aftermarket headlights using a different connector or wiring configuration
 
Important
 
This version of the harness does not support AFS or automatic headlight leveling.
 
AFS and automatic leveling should be disabled through coding when applicable to prevent related fault codes.
 
A separate AFS specific harness is available for conversions requiring the factory AFS and automatic leveling functions.
 
Please confirm that your vehicle has the factory 10 pin halogen headlight connector and that your replacement headlights use the OEM 14 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?
 
MK7 vehicles equipped with factory halogen headlights use a 10 pin wiring configuration that does not directly connect to OEM 14 pin Bi Xenon headlights.
 
This harness adapts the required lighting circuits to the OEM 14 pin Bi Xenon configuration while keeping the original vehicle wiring intact, providing a clean and reversible installation.
