DESCRIPTION
The ignition lock cylinder is typically mounted below turn signal switch and is actuated by ignition key. The ignition switch is typically mounted at base of steering column, inside channel section of brake pedal support.
The ignition switch is actuated by a rod and rack assembly. A portion of rack is toothed and engages a gear on end of lock cylinder. This enables the rod and rack to be moved axially, with respect to column, to actuate ignition switch when lock cylinder is rotated.
