The COGENG Universal Wiring Harness Set is a premium-quality, OEM-compatible electrical wiring assembly designed for Komatsu multi-model excavators. This harness set is engineered to replace 8260-06-1510 and 20Y-06-31660 – two commonly used wiring harness sections in Komatsu excavators.
This universal harness set serves as a power distribution and signal transmission backbone, connecting key electrical components such as:
Fuse/Relay Panels – Power distribution modules
Starter Motor Circuit – Cranking system wiring
Alternator Circuit – Charging system wiring
Chassis Ground Points – Frame and engine grounds
Instrument Panel / Monitor – Signal and power feeds
ECU (Engine Control Unit) – Sensor and actuator power
Manufactured under ISO9001 certified processes, the COGENG universal harness uses 99.9% pure copper conductors (tin-plated for corrosion resistance) and heat/oil-resistant PVC insulation to withstand the harsh environment of heavy construction equipment – constant vibration, temperature extremes (-40°C to +120°C), and exposure to diesel fuel, hydraulic oil, and abrasive debris.
