Installation decomposition diagram
These two part numbers correspond to Hitachi excavator wiring harnesses for the EX400-3 model (which also covers EX400LC-3 and EX400-3C).
The key difference between the two part numbers is their location:
-
0001302 Hitachi Wiring Harness: This is the Inner (or Internal/Cabin) wiring harness.
-
0001303 Hitachi Wiring Harness: This is the External (or Outer/Main) wiring harness, often associated with the hydraulic pump outside connectors.
Both are critical electrical components for the Hitachi EX400-3 series excavators.
If you're looking to purchase one of these, you should confirm the exact model and series of your excavator to ensure compatibility.
Do you need help finding a supplier, or are you looking for more technical information about these harnesses?
