Installation Notes

Verify the connector shape, terminal count, and screw-on mounting style before installation. Match the vehicle application exactly, especially on Toyota Corolla, Subaru Forester, and Mazda Miata models where multiple sensor configurations may exist across model years. Confirm the sensor location and thread engagement before tightening.
