Well, the IAT (Intake Air Temperature) sensor is located on the air intake duct between the filter and the throttle body (Assuming you have the 6L motor). The wires are easily visible at the plug that connects the sensor to the wiring harness. That's the easiest place to access them.

I dont understand why you would need that unless you took off all the wires and took out all the plugs and forgot how the wires were.I have the same truck and I always do the plugs and wires one at time to make sure I make a mistake.If this is your ploblem let me know because i might be able to walk you though it.

First...this is where the pump is (gas tank) on the engines listed:
Illustrating fuel pump and sending unit sensor (3) on 1999-2005 4.8L, 5.3L, 6.0L Engines
Removal & Installation
WARNING Do not handle the fuel sender assembly by the fuel pipes. The amount of leverage generated by handling the fuel pipes could damage the joints.

Well the wire and boot may come off together or seperate.I have never had any luck with them.6 out of 8 can be reused by the time I get done with them.The steel covers have springs in the bottom of them and the boots are just shoved into them.Try twisting the steel and pull in the boot part.There is not a lot to get a grip on them.After the first try I now just replace the wires and go with 6" aftermarket boot protecters.I get taylor cable, the ones that are rated @1200Deg.Not cheep put next time have a 6" grip to pull on.Never under stood the concept of shoving a plug boot into a steel cover that sits next to the exhaust manifold.

undo the wire first by sliding a thin blade screwdriver under the tab. lift slightly and pull the connector off. Use a pair of waterpump pliers or slip joint pliers and turn the body of the actuator out as if undoing a bolt(counterclockwise). It comes out real easy.
