Installation Notes and Tips

Verify the connector shape, terminal count, and mounting style before installation. This part uses a snap-fit attachment and a single square connector, so matching the original switch configuration is important for proper fitment. Confirm the vehicle build date on 1997 BMW 528i and 540i applications, since the fitment notes specify from 3/97.
