Where is the Throttle Position Sensor on a 1984 Ford Bronco II?

Beside the carb. I would tap the IAC with a very small hammer to try and free up the junk inside. It gets clogged with exhaust gas carbon, black soot, etc. If it is clogged you can take it off and clean it with varsol, carb cleaner, wire brush etc and save the price of a new one.
