Application

The 342-2890 Wiring Harness functions as a Fuse Box Assembly Wiring Harness (also referenced as Harness AS-PANEL or EFI Fuse Box Assembly Wiring Harness) specifically engineered for 70-ton class hydraulic excavator platforms. This harness serves as the critical electrical interface connecting the operator cab's fuse box assembly to the main electrical distribution system, facilitating comprehensive power distribution and circuit protection for critical machine components.

It is extensively utilized across multiple heavy-duty excavation equipment configurations, including standard excavator models and long boom variants. The harness is compatible with machines powered by 15.2-liter and 18.0-liter displacement diesel engines featuring turbocharging and air-to-air aftercooling technology, supporting the electrical infrastructure for cab-mounted fuse boxes, relay panels, circuit breakers, and distribution terminals.
