Who. Me?

2007 Leon Stylance 1.9tdi with factory bluetooth kit.

I'm replacing the factory head unit, using a Connects2 kit to integrate with the steering wheel controls etc. The new headunit (second hand Kenwood unit) has a microphone-in option and I'd like to connect it to the factory-installed microphone in the interior light cluster that came with the factory bluetooth.

What route does the microphone wire follow from the interior lamp unit to the bluetooth unit that is under the seat? And to save me pulling the lamp unit out, what wire colour am I looking for?

Thanks
