It is a bundle of wires used for signal communication between the ECU (engine control unit) and devices and for supplying power from the battery to ensure a safe and comfortable ride, and is the most important core circuit of the vehicle.
A variety of technologies are used to improve the functionality of the product, such as using heat-resistant materials in high-temperature areas near the engine and noise-preventing wires in sensor circuits with weak currents.

Control wiring is installed inside the cabin of construction machinery, the part in which the operator sits and operates the machinery.

Power supply circuits and earth circuits that supply the necessary power to each device in the vehicle.
Since a larger current flows through it than through a signal circuit, it uses thicker wires, and a fuse unit is built in to prevent short circuits.

A harness that connects to various devices to transmit energy and control operations.
It plays an important role in maintaining the efficiency and performance of the entire hydraulic system.

A harness for connecting an around camera that shows the area around the construction machinery body and a rear monitor.

The contents of the harness vary depending on the area and conditions of use.
- FUEL HARNESS
Sensor circuit for detecting power supply to fuel pump and total fuel level
- BRAKE SWITCH HARNESS
Signal transmission circuit for stop lamps linked to brake operation
- STARTER SWITCH HARNESS
Signal transmission circuit to the relay that turns the starter motor
