Installation Notes and Tips
Verify the connector shape, terminal count, and external mounting location before installation. Compare the original sensor to the AS74 unit and confirm OE reference 89460-35030 where applicable. Because mounting hardware, brackets, O-rings, and wiring harness are not included, reuse or source the required vehicle-specific components as needed.
