Installation Notes and Tips

Install the KS98T on the original bolt-mount location and verify the connector seats fully into the female plug-in terminal. Inspect the harness and mounting surface before installation so the sensor can read engine vibration accurately. For Subaru Forester, Impreza, Legacy, and Outback models, confirm the part number and connector style against the original sensor before replacement.
