Under the rear of the resonator box at the front of the engine. Just infront of where the butterfly valve for the engine intake.
The IAT sensor is probably on the throttle body and you hook you module to the dianostics connector just under the driver side of the dash.
I found what I think the IAT is located on the 08 xD (I have one). It is in the MAF near the throttle body and is a combination Air Flow Sensor and Air temp assembly. The leftmost 2 wires are connected to the IAT (you can see the thermistor) and on mine, the wires are the green and yellow ones going to the plug assembly. I put a 4.7K resistor across (paralleled) the sensor, and hope to have a better low end performance when I try it tomorrow. The 4.7k resistor should simulate 57 degree incomig air and add more fuel and advance the timing aprox 1.5 degrees (so I read) hope this answers your question Aloha from Hawaii - no 57 degree incoming air here :>)
Or was the Supercharged hemi powered 57 Nomad the first car he stole.
