This harness is designed to convert North American-spec MK8 / MK8.5 vehicles for use with European-spec IQ tail lights or compatible aftermarket Euro-style lights. It offers a clean, plug-and-play installation with no coding, pinning, or repinning required, ensuring an OEM-level fit and reliable operation.

Separate Brake Signal Function

Reviews
I have previously used competitor's harnesses on my MK7 and this harness is my favourite one I've used to date. The connectors come without the pins installed, so it makes it super easy to run the wiring through the grommets. Installing the pins is very easy as well since they are all colour coded. All functionality works perfectly. Dynamic signals and brake lights with signals on. MK6ix was great to answer questions too on a Sunday night, definitely the best harness experience I've had.
