Hi,

Here are directions:

  2. If equipped, remove the tilt lever.

  3. Remove the upper and lower steering column covers with a suitable Torx® driver.

  4. Using Snap-On® tamper-proof bit TTXR20BO or equivalent, remove the ignition switch screws.

Do not remove the cylinder at this time.

  1. Turn the key to the LOCK position and remove the key.

  2. Remove the ignition lock.

To install:

  1. Install the electrical connectors to the switch. Ensure the switch locking tabs are fully seated in the wiring connectors.

  2. Mount the ignition switch to the column. The dowel pin on the ignition switch assembly must engage with the column park-lock slider linkage. Ensure the ignition switch is in the lock position (flag is parallel with the ignition switch terminals).

  1. Apply a dab of grease to the flag and pin. Position the park-lock link and slider to mid-travel. Position the ignition lock against the lock housing face. Ensure the pin is inserted into the park-lock link contour slot and tighten the retaining screw.

  2. With the ignition lock and switch in the LOCK position, insert the lock into the switch assembly until it bottoms.
