Section 11-05: Steering Column Switches
1993 Mustang Workshop Manual
DESCRIPTION AND OPERATION

Ignition Switch

The ignition switch is mounted on the lock cylinder housing and is controlled by the lock cylinder through a pin which is part of the actuator assembly.

The lock cylinder also controls the mechanism which provides a positive lock for the transmission linkage and the steering system. The locking mechanism is located in the lock cylinder housing at the upper end of the steering column.

The lock cylinder positions are ACC, LOCK, OFF, RUN and START. With column shift automatic transmissions, the lock cylinder key can be removed from the lock cylinder only when the shift lever is in PARK position and the key is in LOCK position. The ACC position operates while the steering and transmission systems remain locked. Turning the key to OFF position shuts off the engine without locking the steering or transmission systems.
