This harness converts a 10-pin car-side loom to run OEM 14-pin Bi-Xenon headlights and is built specifically for Golf R bumper installs on the MK6/PQ35 platform. It preserves the Golf R lighting logic and eliminates tapping the Central Electronics module (CECM/J519) for a high-beam trigger—the shutter signal is handled within the harness.
 
Key Features
10-pin → 14-pin conversion for OEM Bi-Xenon housings.
No CECM/J519 tap for high beam: internal high-beam/shutter trigger path.
Designed around Golf R bumper installs (routing and lengths optimized for the R front end).
Retains low beam, high beam (bi-xenon shutter), DRL, turn, and marker functions.
OEM-style connectors, correct gauge, clean strain relief.
 
AFS / Auto-Leveling
OEM 14-pin Bi-Xenon supports AFS/leveling, this harness does not.
If AFS/leveling are enabled in your car, faults may appear—disable in coding for a clean scan.
If you need full AFS/leveling, use the AFS-specific harness (separate product).
 
Fitment & Notes
For MK6/PQ35 Golf R bumper retrofits using OEM 14-pin Bi-Xenon headlights.
Works for Golf R and for MK6 Golf/GTI owners doing an R bumper + OEM 14-pin headlight conversion.
Not intended for aftermarket housings or non-R bumper layouts.
If you’re unsure, send VIN and connector photos and I’ll confirm before you order.
 
Why This Harness
Generic 10→14 adapters often require a J519 high-beam tap and don’t account for Golf R-specific front-end wiring. This harness is mapped for the R bumper and carries the shutter trigger internally, so you avoid opening the CECM and splicing into high-beam circuits.
