Where is the IAT wiring located on a 2000 Silverado 4.8?

The Intake Air Temperature (IAT) sensor wiring on a 2000 Silverado 4.8 is typically located near the air intake manifold, specifically in the air intake duct or the air filter housing. The IAT sensor itself is usually mounted directly in the intake manifold or the air intake tube. You may need to trace the wiring harness from the sensor to locate the connector and check for any issues. Always consult your vehicle's service manual for specific details related to wiring diagrams and sensor locations.
