On your throttle body near the intake manifold. Not sure on the 94 but there should be a MAF on top, then as you move in you will find the TPS on the front, and the IAC is just past that and a little above the TPS.

Your mileage may vary, but the IAC is on the upper-left of the front of the throttle body. On mine, it'* the only sensor held in by regular Torx screws (as opposed to Torx Security screws).
Important note: it may seem like a good test, but unless you like playing "find the pintle," don't power up the car with the IAC out. (If you do, I know from experience that it usually lands up near the wiper blades.)
