Installation Notes and Tips

Verify connector shape, terminal count, and harness length against the original sensor before installation. Inspect the wiring path and connector lock for damage, and confirm the sensor seats correctly in the original mounting location. Because no mounting bracket is included, reuse the existing bracket or mounting arrangement if your vehicle requires one.
