The ignition switch is usually mounted to the steering column and is operated by a linkage rod.
On column-mounted ignition switches, don't confuse the switch with the lock cylinder and keys. The ignition switch is not normally visible.
On some vehicles, the steering column support has to be removed and the column lowered to find the ignition switch. On others, the switch is accessible under the dash.

- Bolt the new switch into position.
- Attach the witing harness.
