The manual TPS will not work on auto trans model, supposedly you must buy a throttle body to get the auto one. Thank Ford for that one. Thinking the voltage range is different........
The IAC is located under the throttle body but inboard of the intake manifold, between intake and engine, you can see it underneath car by skootchying up under car and viewing the space between engine and the intake. It bolts to the black plastic of the intake with two bolts.
Both those contentions hinge on the engine being zetec or 16 valve which it says somewhere on top of engine.
