Need Help

[kmdeuce]

I have an 04 Silverado w/ a 5.3L V8 I am trying to locate the CTS coolant temperature sensor or the IAT Air temp sensor. Can anyone give me an idea where it may be located or color of wires? There are supposed to be two wires and by the thermostat, but I can't seem to locate.
I appreciate any help.

Thanks

I think if you looking for the outside air temp it's on my right side radiator you can see if you remove fan shroud cover i have 03
