Installation Notes and Tips

Verify connector style, terminal layout, and vehicle application before installation. The sensor uses a round, female connector with a male bullet terminal, so matching the electrical connection is important for proper fitment. Because mounting hardware and wiring harness are not included, inspect the existing harness and mounting point for wear, corrosion, or damage before replacing the sensor. For best results, confirm the part number 242-1080 against the original sensor and vehicle service information.
