This harness adapts the factory 10-pin headlight wiring to work with OEM 14-pin Bi-Xenon headlights. It’s built specifically for MK6 PQ35 cars converting from halogen/10-pin to OEM Xenon/14-pin.
 
Key Features
Converts 10-pin car-side wiring to OEM 14-pin Bi-Xenon headlights
Retains core functions: low beam, high beam, DRL, markers
OEM-style connectors with proper wire gauge and sleeving
Plug-and-play design, no splicing required
Factory-like fit and finish for a clean install
 
AFS / Auto-Leveling
OEM 14-pin headlights normally support AFS (Adaptive Front Lighting System) and auto-leveling
This harness does not support AFS or auto-leveling — those systems must be disabled in coding to prevent error codes
If you need AFS functionality, use the dedicated AFS harness (sold separately)
 
Fitment & Compatibility
Designed for MK6 PQ35 10-pin → 14-pin conversions
Not intended for aftermarket headlights — this is for OEM 14-pin Bi-Xenon headlights only
If you’re unsure which harness you need, send me photos of your connectors or your VIN and I’ll confirm before you order
 
Why Use This Harness
OEM Bi-Xenon headlights on the MK6 platform require a 14-pin connection. If your car came with halogen headlights (10-pin), they won’t plug in directly. This adapter bridges the difference, giving you a clean, OEM-style solution to run 14-pin Xenons without splicing.
 
Notes
Disconnect the battery before wiring work
Does not provide AFS or auto-leveling support
Confirm your headlight connector type (10-pin car side to 14-pin OEM Xenon) before ordering
