This harness enables installation of AlpTech LED Euro taillights on MK6.5 Jetta models (both pre-facelift and facelift) by matching their 5-pin sequential wiring layout.
Key Features
Supports sequential signal functionality used by AlpTech LED tails
Plug-and-play design, no complicated wire cutting
Works with both pre-facelift and facelift Jetta models
Engineered to handle AlpTech’s unique wiring scheme
Fitment & Compatibility
MK6.5 Jetta (pre-facelift & facelift) — Compatible with AlpTech LED tails
Not compatible with facelift GLI LED taillights (their wiring integrates brake + signal in one circuit)
For GLI LED tails, use the dedicated harness listed elsewhere
Important: Make sure your tail wiring layout matches AlpTech’s 5-pin sequential configuration before buying. If you’re unsure, send me your tail connector photos or your VIN and I’ll verify it for you.
Why This Harness
AlpTech LED tails use a 5-pin layout with sequential turn signals. Without an adapter, those signals won’t work properly. This harness bridges the factory wiring to AlpTech’s standard so your new tails function as intended.
Notes
Does not support GLI LED tail light wiring — see GLI version harness
Always disconnect the battery before wiring
Harness includes both inner and outer side components
