MAP/IAT Wiring diagram

Anyone have this wiring schematic for the mass airflow/intake air temp. sensor? Short of that, does anyone know which of the two wires are specifically for the IAT sensor?

Really need to make sure I'm playing with the right wires......

Thanks!

I will try to take a look at the service manual later tonight to see what is in there.

2007 3.7L
From Run Crank Relay: Pink
Ground: Black/White
MAF Sensor Input to ECM: Yellow
IAT Low Reference: Black
IAT Signal: Light Blue

Accurate per Service Manual for 2007 Model year. 2006 is different, and not sure about 2008 to current.
Thank you, USVibrant.

That's WAS a big help.....except for some reason the light blue wire on MY 2007 H3 is actually tan.....weird, but hey.....ALL the other colors were correct, so it was a simple matter to check the tan wire with an ohm/volt meter too make sure it was in fact the IAT sensor lead.

Thanks much for your help!

Now if I could only find some good under carriage protection for less than an arm and 1/2 a leg!!!
