The COGENG External Wiring Harness, part number 20Y-06-41110 (20Y0641110), is a precision-manufactured electrical distribution harness engineered as a direct replacement for the Komatsu PC200-6 and PC220-6 hydraulic excavator platforms. These 20- to 22-ton class excavators belong to Komatsu's globally deployed Dash-6 generation, widely used in construction, road building, utility installation, quarry, and general earthmoving applications.
This harness is an external / chassis wiring harness, providing the electrical link between the engine compartment and the machine chassis. It carries power and control signals for the engine ECU, alternator, starter motor, sensors, and various actuators. A damaged or degraded external harness can cause intermittent fault codes, sensor errors, engine derate, hard starting, or complete electrical failure.
The 20Y-06-41110 is part of a related harness family that includes 20Y-06-41111, 20Y-06-41112, and 20Y-06-41113, which represent production revisions or configuration variants for the same PC200-6 / PC220-6 application. The COGENG replacement is engineered to match OEM routing, branch lengths, and connector positions for a drop-in installation.
Critical Note: This harness is verified for the Dash-6 generation (PC200-6 / PC220-6). It is not verified for the PC200-8 or PC270-8 (Dash-8 generation), which use a different electrical architecture and harness family. If your machine is a -8 series, please contact us with the serial number and old part number for correct identification.
| Brand | Model | Machine Class |
|---|---|---|
| Komatsu | PC200-6 | 20-Ton Hydraulic Excavator |
| Komatsu | PC200LC-6 | 20-Ton Hydraulic Excavator (Long Crawler) |
| Komatsu | PC220-6 | 22-Ton Hydraulic Excavator |
| Komatsu | PC220LC-6 | 22-Ton Hydraulic Excavator (Long Crawler) |
Note: The PC200-8 and PC270-8 are not verified for this part number. Verification with your machine's complete serial number is mandatory.
Complete External Wiring Harness Assembly (1 unit): Fully assembled harness with all connectors, terminals, protective conduit sheathing, factory-positioned P-clips, and identification labels pre-installed.
All Sensor, Actuator, and System Connectors: Every branch is pre-terminated with the correct sealed contacts and silicone wire seals.
High-Current Power and Ground Terminals: Heavy-gauge alternator, starter motor, and battery cables terminated with appropriate ring terminals, sealed with heat shrink.
PP Bag Inner Packing and Export Carton: The harness is sealed in a PP bag with anti-static protection and flat-packed in a rigid, double-wall corrugated carton with custom-cut protective foam.
Generation Specificity — NOT for -8 Series: The 20Y-06-41110 is verified for the Dash-6 generation (PC200-6 / PC220-6). It is not verified for the PC200-8 or PC270-8 (Dash-8 generation), which use a different harness family and connector architecture. Do not order this part for a -8 series machine without explicit verification.
Part Number Family: The 20Y-06-41110, 41111, 41112, and 41113 are related references for the same PC200-6 / PC220-6 harness application. They may represent production revisions or configuration variants. Our technical team will verify the correct configuration for your machine serial number.
Serial Number Verification is Mandatory: Komatsu implemented running production changes within the Dash-6 series. Providing your complete machine serial number allows our technical team to verify the exact harness variant your machine requires.
External Harness Section: The 20Y-06-41110 is an external / chassis harness. It is not the internal cab harness or the complete machine harness. Please verify the specific section you are replacing before ordering.
Professional Installation Required: Installing an external wiring harness requires methodical routing through the engine bay and chassis, proper securing at all mounting points, and verification of all connections. Installation should be performed by a qualified heavy equipment technician with access to the Komatsu service manual and diagnostic software.
Step 1: Safety Lockout and Documentation — Disconnect battery cables. Photograph existing harness routing and all connector orientations.
Step 2: Old Harness Removal — Label every connector. Disconnect ECU, sensors, alternator, starter, and chassis interface connectors. Release P-clips and extract old harness.
Step 3: New Harness Comparison — Compare connector types, branch lengths, and mounting clip positions against the old harness.
Step 4: Routing and Connection — Route following the photographic reference. Connect the controller connector first, then all sensor/actuator branches. Torque power terminals to OEM specifications.
Step 5: Power-Up and Functional Test — Reconnect batteries. Connect Komatsu diagnostic software. Verify no active fault codes. Start engine and verify all parameters.
