381100403 XCMG GR2605 motor grader engine wiring harness

381100403 XCMG GR2605 motor grader engine wiring harness

Core Product Advantages

**Original Factory Precise Compatibility:** Designed specifically for the GR2605 motor grader engine’s electronic control system, the interface, pins, length, and routing are perfectly matched to the original vehicle, allowing for direct replacement without rewiring. Compatible with Cummins series engines.

**High Temperature and Aging Resistance:** Utilizes special cables and insulation layers resistant to temperatures exceeding 125℃, enduring high engine compartment temperatures, oil contamination, and vibration. Long-term use is resistant to hardening, cracking, and short circuits.

**Waterproof, Oil-proof, and Sealed:** All connectors feature waterproof rubber rings, and the wiring harness is covered with corrugated tubing and wear-resistant tape, providing a high level of overall protection, suitable for dusty, humid, and oily construction environments.

**Stable Signal and Interference Resistance:** Critical signal lines are shielded to reduce electromagnetic interference, ensuring accurate signal transmission from the ECU, sensors, and actuators, preventing unstable idling, abnormal power, and false fault codes.

**Durable and Vibration-Resistant Structure:** Multi-stranded wires and securely crimped terminals withstand strong equipment vibration. Connectors have a tensile strength of ≥90N, ensuring no loosening or poor contact even after long-term use.

Easy Installation: Comes with original factory fixing clips and cable ties, ensuring standardized wiring, reducing wear and tear, and facilitating efficient maintenance and replacement.
