After you gain access to the cable, this is what you will find underneath the radio/console just forward of the shifter.

Pinch the two "tangs" to unlock the cable. The lock can only go in one way.
After disconnecting the cable from the throttle pedal, attach a heavy duty string or wire.
After removing whatever is necessary under the center console plus the ECM area and of course the engine end, have a friend
SLOWLY pull on the disconnected cable from the engine side while you watch for any snags on the way out.
Needless to say, install by pulling on the gas pedal end while you or your friend feed the new cable into the car.
Foe me the hardest part was getting my hand forward enough to disconnect the lock.
The Fiero Store has them for $49.95
Mine from the Fiero Store has been in the car for years without a problem.
