The question I have is when I go to the stock AFM harness I have no idea which wire does what. Basicly I have the MAF Ouput wire, + 12V, Ground, and Temp signal that have to be hooked up. The kit came w/ no instructions for this. Anybody have the correct wiring colors or pin configuration for these wires @ the AFM? I would really appreciate the help.
Thanks:

I'm not familiar with the PMAS MAF, but as far as where to mount the electronics, take a look at the metal panel under the pasenger side floor board (next to the DME on late cars) as thats where I mounted my piggyback.
If you don't have room there, slide out the cubby in the center console (under the radio) and you can install it behind there.
As for wiring, you need to find a set of factory wiring diagrams (they have pin numbers and wire colors), which are in the factory service manuals, which are available in .pdf format (and hence online, google is your friend).
Edit: after re-reading, the wire output for the AFM are +5, GND, AFM signal, and Temp signal (resistive). So it looks like you'll need to tap into another 12v source, perhaps the DME power, or something else relayed by the ignition.
