Were is the air flow sensor on a 1997 Dodge truck with 360 engine?

On a 1997 Dodge truck with a 360 engine, the Air Flow Sensor (AFS) or Mass Airflow Sensor (MAF) is located in the air intake tube, between the air filter housing and the throttle body. It's a fairly large sensor, usually rectangular or somewhat oblong in shape, and will have a wire harness plugged into it. You'll need to trace the air intake tube from the air filter to find it.
