Installation decomposition diagram
Important Safety Notice: Always refer to the official JCB service manual for your specific excavator model before beginning installation. Incorrect installation may result in electrical system damage or machine malfunction.


  1. complete Power Shutdown: Turn off the excavator and disconnect all battery connections. Activate the main power isolation switch if equipped and wait at least 10 minutes for system capacitors to discharge completely

  2. Thorough Pre-Installation Documentation: Photograph the existing harness routing, connector positions, and cable securing points from multiple angles for reference during installation

  3. Careful Connector Handling: Release all locking mechanisms before disconnection. Pull only on connector housings, never on wires, to prevent terminal damage

  4. Comprehensive Component Inspection: Examine all sensors, control units, and mating connectors for signs of wear, corrosion, or damage before installing the new harness

  5. Precise Routing Installation: Follow the original factory routing exactly, ensuring the harness is properly seated in all clamps, guides, and protective conduits

  6. Secure Connection Verification: Push each connector until audibly locked. Gently tug to confirm secure engagement and verify all weatherproofing seals are properly positioned

  7. System Function Verification: Reconnect batteries and power up the system. Check for diagnostic codes and verify proper operation of all electrical functions before returning to service
