Installation Notes and Tips

Verify connector style, terminal count, and mounting location before installation. This sensor uses an oval, 3-terminal male connector and includes a mounting bracket, so matching the original configuration is important for proper fitment. For best results, inspect the connector, wiring, and sealing surfaces during replacement and confirm the O-ring condition where applicable.
