SK200-6 INNER Wire Harness

Product Overview

The Inner Wire Harness is the primary electrical backbone inside the cab of your Kobelco SK200-6 or SK210-6 excavator. This comprehensive harness routes power and control signals to all interior components, ensuring seamless communication between the operator and the machine’s various electronic systems.

The SK200-6 and SK210-6 series, including the SK200LC-6, SK210LC-6, and SK210NLC-6 variants, represent Kobelco’s -6 generation of hydraulic excavators. These machines feature sophisticated “Mechatro Control” systems that integrate electronic control with hydraulic operation . The inner wire harness is critical to this system, carrying signals from operator controls to the machine controllers and displaying critical machine data to the operator.

Installed inside the cab, this harness is protected from direct weather exposure but remains subject to vibration, temperature fluctuations, and potential moisture intrusion. Over time, connectors can corrode, wires can chafe against metal supports, and insulation can become brittle . The result is often intermittent electrical problems that are notoriously difficult to diagnose—flickering displays, non-responsive switches, or complete loss of cab functions .

Installing a new LQ13E01313P9 inner wire harness provides a permanent solution to cab-related electrical issues, restoring full functionality to your machine’s operator station.

Key Features

• Full Cab Coverage: Includes all necessary wiring branches for the monitor panel, main controller, joystick sensors, switch banks, HVAC controls, and power distribution points.

• OEM Specification Construction: Manufactured using high-quality, cross-linked polyethylene (XLPE) insulated wire designed to resist wear and maintain flexibility over time .

• Precision Connector Fitment: Features OEM-grade connectors that lock securely onto the monitor panel, controllers, and all cab components.

Components Connected by the Inner Harness

The inner wire harness interconnects all critical electrical systems within the cab of the SK200-6 and SK210-6:

• Monitor Panel (Display): Provides power and signal for machine data display, warning lamps, and diagnostic information

• Main Machine Controller (ECU): The central processing unit for the Mechatro Control system 

• Hydraulic Pump Controller: Communicates with the main controller for pump flow control

• Joystick Sensor Assemblies: Transmits operator input signals for proportional hydraulic control

• Switch Panels: Rocker switches for lights, wipers, travel speed, work mode selection, and auxiliary functions

• Throttle Control Dial: Sends engine speed setting to the governor controller

• Key Switch Assembly: Main power and start circuits

• HVAC Controls: Heater and air conditioner panel connections

• Fuse Box / Relay Panel: Power distribution and circuit protection

• Travel Control Pedals: Sensor or switch connections for travel functions

• Safety Switches: Seat belt, armrest, and emergency stop circuits

• Cab Lighting: Interior dome lights and convenience lighting

• Radio / Audio System: Entertainment system connections (if equipped)

• 12V Power Outlet: Accessory power

Signs Your Inner Harness Needs Replacement

The inner wire harness is subject to gradual degradation due to vibration, temperature cycling, and moisture exposure. Replace your inner harness if you observe:

1. Monitor Display Issues: The monitor panel flickers, displays incorrect information, fails to power up, or shows garbled data.

2. Intermittent Warning Lights: Warning lamps illuminate randomly or fail to function as expected during normal operation.

3. Non-Responsive Switches: Various cab switches (lights, wipers, work mode, travel speed) fail to operate or work intermittently.

4. Erratic Joystick Control: The excavator responds unpredictably to joystick commands due to intermittent sensor signal loss.

5. Machine Will Not Start: Complete electrical failure in the cab preventing engine cranking or start sequence initiation.

6. Blown Fuses: Repeated fuse failures indicate damaged wiring causing shorts to ground.

7. Visible Harness Damage: Cracked, melted, frayed, or chafed wire insulation visible behind panels, under the floor, or near the controller mounting area.

8. Corroded Connectors: Green or white oxidation visible on connector terminals, particularly at high-use connection points.

9. Previous Repairs: The harness shows evidence of multiple previous splices, taped sections, or bypassed circuits, indicating degraded reliability.

10. Diagnostic Communication Failure: Diagnostic tools cannot communicate with the machine controller due to harness bus communication issues.

The Mechatro Control System

The SK200-6 and SK210-6 series feature Kobelco’s advanced Mechatro Control System, an integrated electronic-hydraulic control system . The inner wire harness is essential to this system, carrying signals between:

• Input Devices: Joysticks, pedals, switches, and sensors

• Controllers: Main machine ECU and hydraulic pump controller 

• Output Devices: Solenoid valves on the main control valve, governor motor, and display components

A damaged inner harness can cause communication failures within this system, leading to reduced performance, error codes, or complete loss of machine functions. Replacing a degraded harness restores proper communication and system performance .

Installation Tips

• Professional Installation Recommended: Inner harness replacement requires significant disassembly of cab panels, operator seat, and floor plates. Professional installation by qualified technicians is strongly recommended.

• Disconnect Battery: Always disconnect the battery ground terminal before starting any electrical work.

• Photograph Original Routing: Take extensive reference photos of the original harness routing before removal, noting every cable tie location, clip position, and connector placement.

• Label Connectors: Use numbered tags to label each connector as it is disconnected, noting the component it serves.

• Remove Panels Carefully: The harness runs behind the monitor panel, under the cab floor, and behind side panels. Remove trim pieces carefully to avoid damage.

• Route the New Harness: Follow the factory routing path exactly, keeping the harness away from sharp edges and moving parts.

• Secure Properly: Use new cable ties at all original attachment points. Avoid overtightening ties that can pinch wires.

• Inspect Connectors: Before connecting the new harness, inspect all component-side connectors for corrosion or damage.

• Verify Ground Connections: Ensure all chassis ground points are clean and secure for proper circuit function.

• Test Before Panel Installation: Before reinstalling panels, reconnect the battery and test all cab functions including monitor display, switches, joystick controls, and HVAC.

• Clear Fault Codes: After installation, use a diagnostic tool to clear any stored fault codes.
