    I'm splicing the wiring for my N75, MAF, check valve, and ICM when I notived there are 3 wires that are color coded red with a green stripe!

    Does anyone know what's up with that. I'm sure they can't be the same unless it's a constant power thing.

    Better question. Who knows what Pin numbers go to what. I can test to see what wires are what if I could get a wiring diagram. I can't find my freakin bentley CD.

    I found this diagram finally.

    http://homepage.ntlworld.com/kevin.y...A4_ECU_AEB.pdf

    according to page 3 section D23 is says that the all 4 red and green wires are "Positive (+) connection (87f), in engine compartment wiring harness, right"

    Someone correct me if I'm wrong. it doesn't matter which goes to which since they are all positive wires.
