3 speed key lock-out

Have a 70, but ripped that out in 71, been a long time. Seems there is a switch under the dash, to the clutch pedal, or the rod going to the steering lock on the column, in the engine bay. It's not on the shifter itself. Can't remember at 62 years old.Seems like it was with the steering wheel lock, not in the column. it was easy to defeat. Sorry, but a little switch ,in plain sight.
