The MAF carries a thermistor which is used by the ECU to correct for Air Inlet Temperature.(AIT?)
IAT? Interior Air Temperature? is sensed by another sensor(s) within the cabin.
Sorry offhand I can't give you the pin-outs but I'm reasonably sure that if you Google "Bosch Mass Air Flow meter" you will find the pin out configuration you require.
