There is a small peddle on the floorboard between the driver and passenger, what function does this perform? It seems to be able to lock into position. Also, there is a key switch at the top of the steering column, right hand side which I do not have a key for, what is the function of this?
I'd say the peddle on the floor went to a cutout on the exhaust system, or to an exhaust whistle, the key lock probrably was a locking accessory steering wheel?
Both items are non-stock. Without seeing these things, all guesses are just that. For the steering column lock my guess is the same as John's. For the pedal, I'd just look under the floor boards and see where it goes.
