Here are the instructions and some diagrams (BELOW) that will help you get the job done.


1. Remove lower instrument panel cover below steering wheel. Remove snap-in panel around ignition key cylinder. Make installation reference marks on all wiring connectors. Disconnect
wiring connectors from steering lock housing and from rear of ignition switch. Turn ignition key to No. 1 position.

Loosen steering lock housing retaining clamp bolt, located near steering column.
In locking pin, located to left of retaining clamp on jacket tubing. Leave retaining clamp on jacket tubing. Pull steering lock housing out of jacket tubing slightly.

Remove ignition key to enable removal of steering lock housing from jacket tubing. With steering lock housing removed from jacket tubing, ignition switch can now be removed from rear of
steering lock housing by removing 3 retaining screws.


1. To install, locate ignition switch locating lug to recess in rear of steering lock housing. Install switch retaining screws. Ensure steering lock and ignition switch mechanisms operate properly.
Install steering lock housing into jacket tubing by pushing inward on housing locking pin and pushing steering lock housing into jacket tubing until bottomed.

2. Ignition key may require turning to engage steering lock housing locking tab into steering column. Ensure steering lock housing locking pin engages in jacket housing hole. Install clamp. Reconnect
wiring connectors. Install lower instrument panel cover below steering wheel and snap-in panel around ignition key cylinder.

Please let me know if you need anything else to get the problem fixed.
