The IAT sensor is a variable resistor whose resistance varies with
temperature.  Put it in series with a resistor as Perry indicated.  +5
to the resistor, other end of the resistor to the IAT sensor, other end
of the IAT sensor to ground.  Then read/log the voltage from where the
IAT sensor is connected to the resistor.  There should be  table of
voltage/temperature values in the service manual.
