I'm trying to identify the 5 circuits on a MAF sensor from a '90 Legacy. Here's what I do know:

Red = 12v+
Black = Signal (0 - 5v)
White = Ground

Here's the two I'm uncertain about:

Blue = ??
Black w/ red stripe = ??

Can anyone with these two?

Thanks,

Brad

Somebody must know what the final two circuits are, no?

Any assistance appreciated - even educated guesses.

Thanks,

Brad
