EVO 8 MAF to 1G wiring

Turbo 1G/GVR4 MAF pinout
Pin 1 = Reset (Green/White)
Pin 2 = Airflow Hz (Green/Blue)
Pin 3 = +12 Volt from MPI (Red)
Pin 4 = +5 Volt Sensor Power (Green/Red)
Pin 5 = Not Connected
Pin 6 = Sensor Ground (Green/Black)
Pin 7 = Barometer (Green/Yellow)
Pin 8 = Intake Air Temp (Green/Orange)

2G/3G/EVO MAF pinout
Pin 1 = +5 Volt Sensor Power (Green/Yellow)
Pin 2 = Barometer (Orange)
Pin 3 = Airflow Hz (Blue/Yellow)
Pin 4 = +12 Volt from MPI (Red)
Pin 5 = Sensor Ground (Black)
Pin 6 = Intake Air Temp (Red/Blue)
Pin 7 = Reset (Red/White)
Pin 8 = Not Connected

So, the correct crossover wiring to our MAF plug is:
3G/EVO Pin 1 to 1G MAF Pin 4
3G/EVO Pin 2 to 1G MAF Pin 7
3G/EVO Pin 3 to 1G MAF Pin 2
3G/EVO Pin 4 to 1G MAF Pin 3
3G/EVO Pin 5 to 1G MAF Pin 6
3G/EVO Pin 6 to 1G MAF Pin 8
3G/EVO Pin 7 to 1G MAF Pin 1

This MAF pinout is the same as a 2G MAF but it's a different connector.

Wire colors included to assist in identifying where pin 1 on each connector is. Your connectors might have different colored wires depending on where they came from. Following the pin to pin connections is what matters.
