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.

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.

Removal & Installation

  1. Before servicing the vehicle, refer to the Precautions section.
  2. Remove or disconnect the following:
    • Negative battery cable
  3. Relieve the fuel system pressure.
  4. Drain the fuel tank.
  5. Remove or disconnect the following:
    • Fuel tank
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.

  • Fuel sender assembly retaining ring using a fuel tank sending unit wrench. Remove the fuel sender assembly and the seal. Discard the seal.
  • Note the position of the fuel strainer on the fuel sender. Support the fuel sender assembly with one hand and grasp the strainer with the other hand. Pull the strainer off the fuel sender. Discard the strainer after inspection. Inspect the strainer. Replace a contaminated strainer and clean the fuel tank.
    • Fuel pump electrical connector
    • Electrical connector retaining clip from the fuel level sensor
    • Sensor electrical connector from under the fuel sender cover
    • Fuel level sensor retaining clip
  • Squeeze the locking tangs and remove the fuel level sensor.
  • Remove the fuel pressure sensor.
  • To install:
    1. Install or connect the following:
      • Fuel pressure sensor
      • Fuel level sensor
      • Sensor retaining clip
      • Electrical connector to the fuel level sensor
      • Electrical connector retaining clip to the fuel level sensor
      • Fuel pump electrical connector
      NOTE Always install a new fuel strainer when replacing the fuel tank fuel pump module.

      • New fuel strainer in the same position as noted during disassembly. Push the strainer on the bottom of the fuel sender until the strainer is fully seated.
      • New seal on the fuel tank
      NOTE The fuel pump strainer must be in a horizontal position when the fuel sender is installed in the tank. When installing the fuel sender assembly, assure that the fuel pump strainer does not block full travel of the float arm.

      • Fuel sender assembly into the fuel tank
      • Fuel sender assembly retaining ring
      • Fuel tank. Install the fuel tank strap attaching bolts. Tighten the bolts to 30 ft. lbs. (40 Nm).
    2. Refill the fuel tank. Install the fuel filler cap. Connect the negative battery cable.
    3. Turn the ignition ON for 2 seconds.
    4. Turn the ignition OFF for 10 seconds.
    5. Turn the ignition ON.
    6. Inspect for fuel leaks

    SOURCE: How do you change spark plugs in a 2002 Sierra

    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.

    SOURCE: 2002 gmc sierra front diff. actuator motor.

    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.
