Centralized Connection Points: The harness is routed to central connection points or junction blocks (often located under the cab or near the main frame hinge), making it easier to disconnect for major component removal.
Clear Circuit Identification: Every wire is stamped with a circuit number that corresponds to the electrical schematic in the service manual. This is an enormous advantage for technicians during troubleshooting.
Modular Design: While complex, the harness is broken down into logical segments (e.g., cab sub-harness, engine harness, valve harness), which simplifies diagnosis and replacement of individual sections rather than the entire loom.
This 231-1692 platform harness is used for 345C excavator.
