IAT sensor chip

I have an IAT sensor chip, but I'm not sure which sensor is exactly the air intake, I have 2 choices that I can see. I've got a 91 4.0 V6. Does anybody have a labled engine map/picture or something that would help?
thanks :)

I am not exactly sure, though I imagine it will be in the intake hose somewhere after the MAF, near the throttle body. Some engines also have the IAT directly in the upper intake manifold, though most cars I see have them in the intake hose. It's pretty obvious once you see one. Is it a 10k resister? That mod actually does add a minor gain, but you need to series of different resisters and a dyno to make sure you're actually making a difference. Usually, the resister they give you has too much resistence and just makes things a lot worse. I've never tried one, let us know how it works out.

I talked to some people and I can put it on my coolant temperature sensor too, so I'm going to put it in tomorrow, and I'll let you know if it makes much of a change
