If I remember correctly, you will only use 2. Which 2, I don't know. You have to use a volt meter, touch 2 terminals of the potentiometer at the same time, rotate the knob of the potentiometer back and forth to see if the resistance changes. If not, continue until you find the right 2. After you find the right 2, simply cut your signal wire from IAT, each end hook up the the 2. I hope you bought the right ohm range potentiometer.
