If you're looking to convert your bi-xenon spec 12-pin harness to a 10-pin OEM spec, you'll need to use a hardwire option since there are no 12-pin female connectors available to create a true plug-and-play unit.
This conversion involves cutting your original harness and using the provided crimps to make the necessary connections. Each wire is labelled to make the process easier, but it's important to have some basic electrical knowledge before attempting this conversion.
Please note that this harness is designed to fit MK4 (PQ34) and MK5 (PQ35) GOLF/JETTA models. Once the conversion is complete, you'll be able to use aftermarket lighting options that are compatible with 10-pin OEM specs.
While this conversion requires some technical know-how, it's a cost-effective way to upgrade your lighting system and improve your vehicle's lighting.
