This harness is for MK7s equipped with the Lighting Package (14-pin Bi-Xenon). It converts the 14-pin wiring to a 10-pin layout so aftermarket headlights plug in and function correctly.

AFS / Auto-Leveling (Important Notes)

Fitment & Compatibility
MK7 / MQB models with Lighting Package (14-pin Bi-Xenon) — Compatible
MK7.5 / Facelift with LED headlights — Not compatible
Standard MK7 halogen models — Not compatible
If unsure, send photos of your headlight connectors or your VIN and I’ll verify
Why Use This Harness
Aftermarket headlight units typically use a 10-pin connector. If your car has the factory 14-pin Bi-Xenon system, they won’t plug in natively. This harness bridges the gap so your new lights function properly — no miswired channels or signal errors.
Notes
Always disconnect the battery before wiring
Not for adaptive or matrix headlight systems
Confirm connector style before purchase

Reviews
This harness is so damn well built, you'd think it's OEM. The connectors have a satisfying click to them as well. This isn't a cheap harness, but I could tell a lot of care went into it, and I truly respect that. Highly highly recommended! Side note: the zip-tie on the long wire is from me and it's temporary, they were not sent like that.
Bought this harness to convert my lighting package lights to aftermarket 7.5 style. Worth every penny, the only harness out there that can make this happen.
If I didn’t know it was an “aftermarket” harness, I could say this is an oem harness. The attention to detail is 11/10
Purchased this harness to equip my LP MK7 GTI with 7.5 style lights. Worked flawlessly you just need to follow the instructions given with the coding. I had some trouble with my harness. John not only provided me with a speedy replacement but continues to provide me with further information so I can do a bit of self DIY. John is top notch guy and this is a top shelf product. Thanks again!
I have been sure to share this harness anywhere I see LP owners looking for a solution!
