SOURCE: 2007 gmc sierra 2500 IAT sensor
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.

take off the cover on the top and bottom of the steering column just behind the wheel. pop the tilt lever out simply just by grabbing it and give it a good tug. then once you have the new switch and you get in there your going to need an inverted torx socket to remove the small bolts that hold the switch to the column. do not move the gear on the new switch make sure it lines up exactly as the old one did!!!!!!!!!!!!

not sure if u mean the ignition lock cylinder or the actual electrical switch but here are all the instructions.
The mechanical switch itself is rod actuated and located under the dash bolted to the steering column. Remove and trim panels to expose the column bracket. mark the location of the shift indicator clip, and remove with a small flathead screw driver. drop the column and it's right there ,I think it's has two 7mm screws holding it on.
If you are talking about the key cylinder itself you will need to remove the steering wheel, remove the plastic lock ring cover, if you have an air bag there is a ring with yellow wres coming in and out if it, this you CANNOT turn this ring w/o causing damag to the unit and rendering your airbag useless and eht airbag light to come on, remove it carefully and set it on top of the column. With a special tool press the locking ring down and remove the snap ring. After the locking ring is removed you expose the turn signal switch/cam, remove the screw on the left of the cam that attaches the turn signal arm to the switch, and remove the emergency flasher button, both should be phillips head. After the arm and button are removes remove the 3 screws that old the switch in place. GENTLY pull up on the switch, making sure not to break the wiring harness. There is a small plastic and copper connector over a torx head crew, remove it with needle nose pliers being careful not to damage it, this is the terminal that make the buzzer go off when you open the door and leave the keys in the ignition. Now remove the torx head screw and slid out the key cylinder. Re-assemble in reverse order.
