Installation Notes and Tips

Verify the vehicle is a 1994-1995 Oldsmobile Achieva or Pontiac Grand Am without Daytime Running Lights before ordering. Confirm the connector style, terminal count, and cruise-control feature set against the original switch. Because this is a bolt-on, column-mounted combination switch, careful alignment during installation helps maintain proper lighting and signal operation.
