Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. This sensor uses a female oblong connector with 3 male terminals and does not include a wiring harness or mounting bracket, so reuse of existing vehicle-side components may be required. Confirm the application against the vehicle’s year, make, and model before replacing the original sensor.
