Okay, the two things you mentioned are the same item. IAT stands for intake air temperature. That is the same as manifold air temp. If you are correct, that sensor needs replaced.
Now here is my concern. When you first turn the key on with the paper clip installed, you should get the code 12, three times, and then a slight delay, and then any trouble codes. Are you getting the 12? Also, if you take a flash light and look into the connector, how many of the ports have a wiring connector in them?
