According to my diagrams for AXX you should have a white and yellow wire, green and yellow wire and a black wire.  The black wire should be the 12V feed.

My car on the other hand (AXX) has a yellow, brown and black wire 

Someone might want to confirm the feed is or isn't the black.

Hopefully this hasn't confused things even more.

Do you perhaps know to which pin on the ecu it connects?

Im installing bwa cylinder head in my NA 2.0 fsi and mine doenst have the maf sensor.
Bought the connector from vw but now need to wire it in somehow.
