The Cab Wiring Harness, often referred to as the cab main harness or the instrument harness, is the central nervous system within the operator's compartment of a Caterpillar 320 excavator. It is a complex, pre-engineered assembly of wires, connectors, terminals, and protective conduits that distributes electrical power and data signals to every control, display, and comfort feature inside the cab. Its design is critical for the machine's operational efficiency, diagnostic capabilities, and overall reliability.
The Caterpillar 320, as a cornerstone model in the D-Series and later generations, features advanced electronics, making the integrity of its wiring harness even more paramount.
This 350-8253 cab wiring harness is used for 307 307E 307E2 excavator.
