Volvo 220D Excavator Wiring Harness — All 4 Sections
The Volvo 220D uses 4 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 |
|---|---|---|
| Main Harness | Many systems affected at the same time | Main Harness group |
| Injector Harness | One cylinder cold or dead | Injector Harness group |
| ECU / Controller Harness | Controller dead or rebooting | ECU / Controller Harness group |
