dude, you're seriously doing some halfass work there. :a:
The IAT sensor is in the front of the intake. It is held on by 2 screws and has 2 wires going into it. It is usually on a runner or on the plenum (sp).
You can see it on my manifold just behind the FP gauge. It has a white plug on it, but the sensor itself is black. I've seen them both colors.
