I got an audi 80 from 92 with a 2,8l for a car that i'm building. a few weeks ago we removed the engine from the old car and cut all the wires that we didn't need but we accidentaly cut 1 to much, the one to the mass air flow sensor. i didnt realize this until weeks later. i have found a connector with wires but i dont know if its the right one. the connector fits the MAF sensor.

according to 12v Pages - The Engine - MMS200 the MAF sensor should be connected to the 12pin connector on the ECU and i've found the wire on that pin that i've cut.

The problem is that from the connector on the MAF sensor there is a blue-black wire (pin number 3) that i dont know were it goes. does anyone have a wiring diagram for this?

Check out this wiring diagram for a 2.8..page 31..shows the three wires and the connections. #3 wire should be Black Green..hard to tell...but you can see it connects to several other components and changes colors (I think)http://12v.org/urs/1996_Audi_Cabriol...g_Diagrams.pdf

no the cable is black-blue and the connector has 4 pins. the one you linked to are from 1996 which is the predecessor to the AAH motor.
