Which MAF wire is the OUTPUT to the ECU?
I'm trying to find which wire from the MAF tells the ECU how much air is flowing. There are 5 wires, and I figure one is ground, one is the supply voltage, one is intake air temp, one is air flow, and one is something else. Any tips? Has anyone hooked up an Apexi SAFC?

Pin 5 on the MAF, pin E27 on the ECM. Green with Black stripe wire. Signal name is VG.
Solid green on MAF pin 1 ECM pin E18 is THA - ambient air temperature, Brown wire on MAF pin 2 ECM pin E19 is THA ground.
MAF pins 3 & 4 (ECM pin E26 is ground) are power and ground respectively.
