Installation Guide

1. Safety First: Disconnect the battery before beginning any electrical work on your outboard.

7. Reconnect Harness: Securely plug the new sensor's connector into the engine's wire harness.
8. Final Check: Reconnect the battery, start the engine, and check for any fault codes or alerts to ensure the sensor is functioning correctly.
