### Installation Procedure

1. If the lock cylinder would not rotate or was seized, perform the following procedure:

1.1. | Install the new ignition switch lock cylinder as required by rotating both the cylinder and the ignition switch to the ON position.

1.2. | Push the lock cylinder into the ignition switch housing until fully seated.

1.3. | You may need to slightly depress the release button as the cylinder passes by the 9/32-inch hole previously drilled in the ignition switch housing.

2. Position the ignition switch into position through the I/P cluster opening.
3. Connect the electrical connectors to the ignition switch.
4. Connect the Passlock™ electrical connector to the ignition switch.
5. Connect the park/lock cable to the ignition switch.
6. Insert the key and turn the ignition lock cylinder to the ON/RUN position.
7. Install the ignition lock cylinder. If you turned the key slightly while removing the lock cylinder, you may have to align the white colored ignition switch rotor (1) with the lock cylinder (2). You can rotate the ignition switch rotor (1) with your finger.
8. Remove the key from the lock cylinder.
9. Position the ignition switch to the I/P.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

10. Install the bolts to the ignition switch.

Tighten
Tighten the bolts to 6 N·m (53 lb in).

11. Install the I/P cluster. Refer to Instrument Cluster Replacement .
12. Install the I/P accessory trim plate. Refer to Instrument Panel Accessory Trim Plate Replacement .
