Part Number: 328‑4399, 3284399
Item Name: Wiring Harness
This 328‑4399 wiring harness serves as the critical electrical connection assembly for wheel‑loader equipment.
It establishes stable power transmission and signal communication between controllers, sensors, hydraulic components, switches and other onboard electrical components, ensuring the whole‑machine electrical system functions normally.
Constructed with heavy‑duty industrial‑grade cables, waterproof connectors and reinforced protective wrapping materials.
This wiring harness delivers excellent performance against vibration, abrasion, dust, moisture and broad temperature fluctuations, perfectly adapting to tough working conditions of construction sites and mining yards.
Precise pin layout and correct connector positioning support direct‑fit installation without extra modification during machine repair work.
It works as a practical replacement component to resolve common electrical failures including intermittent signal dropout, circuit short‑circuit, open‑circuit faults and component non‑response caused by aging, cracking or harness damage.
Every harness undergoes strict continuity and connectivity testing before shipment to guarantee stable circuit performance.
Compatible Wheel Loader Models: 966H, 972H
