Desciption

Parts List (Typical Set Contents)

This "universal" set may include the following components (varies by application):

Component Quantity Description
Main Power Harness 1 Heavy-gauge power distribution cable
Relay Harness Section 1 Wiring for starter/fan relays
Fuse Box Harness 1 Connects to fuse/relay panel
Ground Cables 2-3 Chassis and engine ground straps
Connector Pigtails As required Pre-terminated Deutsch/AMP connectors

Part Number Reference & Cross-Reference

Referenced Part Number Likely Component Type Typical Application
20Y-06-31660 40A Fuse / Fusible Link PC340-7, PC210-10 (power distribution)
8260-06-1510 Wiring Harness Section Various Komatsu models (verify)
208-06-A1220 Wiring Harness Section Various Komatsu models (verify)
208-06-A1221 Wiring Harness Section Various Komatsu models (verify)

⚠️ 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.

Compatibility Notes

✅ 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:

Check Item Why It's Important
Your Exact Komatsu Model Harness length and connector pinouts vary by model
Old Part Number Confirm the part you're replacing matches one of the numbers listed
Physical Appearance Take a photo of the old harness/fuse/relay and send to supplier
Connector Types Ensure the harness connectors match your machine's wiring
Circuit Configuration Pinout diagrams are essential for "universal" harnesses

❌ NOT Universal For:

  • Komatsu models with different electrical architectures (older/newer series)

  • Machines with aftermarket modifications

  • 12V electrical systems

  • Non-Komatsu equipment without adapter harnesses

Frequently Asked Questions

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.
