Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. The sensor uses a female oblong connector, male blade terminals, and a single mounting hole, so matching the OE connector and sensor body dimensions is important. Confirm vehicle application by year and model before ordering, especially for Saturn L300, Saturn LW300, Saturn LS2, and Saturn LW2.
