Well i'm working over here on a friend's car, and we need to figure out which wire is the signal wire off of the MAF (goin to the ECU)... we are running a piggyback fuel controller on it. I remember hearing somewhere that it is the light blue colored wire, but can't remember for sure
either the color of this wire, or a pinout from the ECU would be great.
also, does anyone know what a good wire to tap for a tach signal would be (preferably off of the ECU itself, I know I could get it off of the back of the gauge cluster).
thanks!

Re: Need to know which wire is signal on a AEG MAF.. and tach signal! (Anand20v)

we tried both the yellow and white wire off of the RPM sensor (G28, right next to the knock sensors), both made the PSC1 think the RPMs were sitting at 10,000 the entire time. as for the MAF wire, we tried the blue wire, and i don't think that was it.
