Disconnect All Power Sources: Turn off the excavator and disconnect the negative battery terminals. Allow 10 minutes for system capacitors to discharge.
Record Existing Layout: Take clear photos of the original harness routing, connector positions, and cable tie locations before removal.
Handle Connectors with Care: Use appropriate tools to release locks—do not pull wires. Check for and avoid bending pins during disconnection.
Inspect Related Components: Examine sensors, solenoids, and controller ports for damage or corrosion. Replace as needed before installing the new harness.
Follow Factory Routing: Install the harness along the original path. Use all designated clips and clamps to avoid contact with hot or moving parts.
Ensure Full Engagement: Push each connector until it clicks into place. Tug gently to confirm it’s secure.
Post-Installation Check: Reconnect batteries and power on the system. Check the dashboard for error codes and verify all engine and control functions operate normally.
