Where is the IAT sensor?

I have a 99' 4 banger, could someone please post a picture, or give me a real good description of where to find the Intake Air Temp sensor?

Now come on.....Step away from the computer and dive under the hood. Even a YJ guy thinks all you have to do is follow the air intake from the front to the motor and look for something with two wires attached????

It's screwed into your intake manifold - it kind of looks like your coolant temperature sensor. It's kind of close to where the throttle body mounts to. It's right before the all the other things with two wires coming out of it (ok, injectors)

I realize that I;m bringing this thread back from the dead. But ... thought I'd drop this in just in case someone else needed help with it.
