Swapping in seats with the red 17-pin connector? This harness adapts them to vehicles with the black 10-pin body connector, making the retrofit plug and play. Seat heating, power adjustment, occupancy sensor, and airbags remain fully functional.

Why This Harness
Seats equipped with the red 17-pin connector do not directly match the black 10-pin body harness found in many MQB cars. This adapter bridges the difference so that all seat functions operate correctly without fault codes or splicing.
 
Notes
Only for MQB seats with red 17-pin connectors into cars with black 10-pin body connectors
Not for 10-pin seat to 10-pin car applications (use the other harness for that)
Always disconnect the battery before working with seat wiring or airbag connectors
