Komatsu D85ESS-2 Wiring Harness — All 3 Sections
The Komatsu D85ESS-2 uses 3 separate harness sections that ECS builds. They are not interchangeable: the part number on your old loom decides which one you need. Below they are grouped by where each section sits on the machine, with the part numbers and the symptoms that point to each group.
Which section do I actually need?
Start from the fault, not from the part name. Find the symptom the operator reports, then open that group.
| Section | First symptom to look for | Group |
|---|---|---|
| Instrument & Interior Harness | One instrument or accessory dead | Instrument & Interior Harness group |
| ECU / Controller Harness | Controller dead or rebooting | ECU / Controller Harness group |
Instrument & Interior Harness 2 parts
It sits inside the cab, behind the trim, feeding the instruments and controls the operator sees and touches.
