Key Features
- Hardwire conversion: cut your existing 12-pin harness and crimp into this adapter
- All wires are individually labeled for easy identification
- Adapts 12-pin Bi-Xenon wiring to 10-pin aftermarket / halogen headlights

- Works with MK4 (PQ34) and MK5 (PQ35) Jetta / Golf platforms
Fitment & Compatibility
- Platforms: MK4 PQ34 and MK5 PQ35
- Use case: adapting a factory 12-pin Bi-Xenon harness to 10-pin aftermarket or halogen headlights
- Compatible with most aftermarket 10-pin housings (no AFS functionality is required since these lights don’t support it)
- If unsure, send photos of your connectors or VIN and I’ll confirm before you order
Why Use This Harness
There’s no true “plug-and-play” 12-pin female to 10-pin adapter available. This harness gives you a proper hardwire solution with labeled wiring, so you can adapt your car cleanly instead of splicing randomly or replacing the entire loom.
Notes
- Requires basic electrical skills and use of crimps
- Always disconnect the battery before cutting or crimping wires
- Confirm pin orientation before finalizing the wiring
