⚠️ Critical Note: The above cross-references are based on publicly available Komatsu parts information. Not all referenced numbers are wiring harnesses – for example, 20Y-06-31660 is known to be a fuse/fusible link, not a wiring harness. This COGENG set may replace that component as part of a complete harness assembly, but fitment is not guaranteed for every application.
✅ Potentially Compatible With:
Komatsu PC200-7, PC210-10, PC340-7 (and other models with matching electrical architecture)
Machines using the referenced OEM part numbers
24V electrical systems (typical for Komatsu excavators)
⚠️ Before purchasing, please verify:

Q1: What is a "universal" wiring harness?
A: A universal harness is designed to fit multiple models with similar electrical configurations. However, it may require minor modifications or verification of connector pinouts to ensure proper fitment for your specific machine.
Q2: Will this harness fit my Komatsu PC340-7?
A: Potentially, but fitment depends on the specific section of the harness you're replacing and your machine's configuration. Verify with your supplier and provide your machine serial number.
Q3: What is 20Y-06-31660 – is it a harness or a fuse?
A: Based on our research, 20Y-06-31660 is a 40A fuse / fusible link, not a wiring harness. This COGENG "universal set" may replace that fuse as part of a larger harness assembly. Confirm with your supplier.
Q4: How do I know if this harness fits my machine?
A: Send the following to your supplier:
Your exact Komatsu model (e.g., PC200-7)
Machine serial number
Photos of the old harness/fuse
The old part number
Q5: Is this a genuine Komatsu part?
A: No. COGENG is an aftermarket manufacturer (ISO9001) . This harness is built to OEM specifications as a cost-effective replacement.
Q6: Does this harness come with a wiring diagram/pinout?
A: We strongly recommend requesting a pinout diagram from your supplier before installation. This is essential for "universal" harnesses to ensure correct connections.
Q7: What is the warranty?
A: COGENG provides a 6-month warranty against manufacturing defects.
Q8: How do I place a trial order?
A: Contact your COGENG distributor. MOQ is 1 set.
