On non-tilt columns:
Move the ignition switch slider to the OFF unlocked position (move the slider all the way down, then back two clicks). The remote rod hole in the ignition switch slider should now be centered.
Insert the remote rod in the ignition switch slider hole and install the ignition switch on the steering column. Tighten the attaching screws to 35 inch lbs. (4 Nm).
On tilt columns:
Insert the ignition key in the lock cylinder and turn the cylinder to the OFF unlocked position.
Move the ignition switch downward to eliminate any slack and tighten the attaching screws to 35 inch lbs. (4 Nm).
Install any components removed for switch access.

Fig. 4: ... then pull out the lock cylinder from the steering column
With the ignition switch still in the ON position, insert a thin screwdriver into the slot adjacent to the switch attaching screw boss (right-hand slot). Depress the spring latch located at the bottom of the slot to release the lock cylinder.
Remove the lock cylinder.
To install the lock cylinder, turn the key to the LOCK position. Insert the lock cylinder in to the housing far enough to contact the drive tang. Force it inward and move the ignition switch actuator rod up and down to align the components. When the components align, the cylinder will move inward and the spring-loaded retainer will snap into place locking the lock cylinder in the housing.
If the lock cylinder is retained by a screw, tighten the screw to 40 inch lbs. (5 Nm).
Install the key warning buzzer switch.
Follow the ignition switch installation procedures to adjust the ignition switch.
Install the turn signal switch.
