Does it matter if the Grey-White and Pink-Black wires on the MAF loom are swapped over? I'm trying to locate connect a new PMAS 75mm MAF, made for a 94-95 Mustang, and loom that came with it has a blue wire and a brown wire. From the diagrams I've seen, one is MAF 5.0 and the other is MAF-RTN.

The electrical diagram in the AU workshop manual doesn't help much.
