The 380501511 Dashboard Harness is a genuine OEM wiring assembly manufactured by XCMG, designed specifically for motor graders and heavy construction equipment. This complete harness connects the instrument panel, sensors, and control modules with reliable power and signal transmission.
Engineered to withstand continuous vibration, temperature extremes, and chemical exposure, the 380501511 harness uses cross-linked polyethylene insulation and tinned copper conductors. It directly replaces damaged or corroded dashboard wiring in XCMG GR series graders.
Each assembly is pre-terminated with original XCMG connectors, ensuring plug-and-play installation without splicing. Restore full functionality of gauges, warning lamps, HVAC controls, and electronic monitoring systems with this OEM-grade component.

The XCMG 380501511 Dashboard Harness is manufactured to the exact original specifications of the factory wiring. Every branch length, connector position, and wire color code matches the service manual. This eliminates guesswork and reduces installation time by more than half compared to universal harnesses.
All terminals are crimped with XCMG-approved tooling, ensuring consistent contact resistance below 10 mΩ. The harness includes protective convoluted tubing at high-wear areas and grommets for firewall passages. Double-locked terminal position assurance (TPA) prevents pin push-out during assembly or vibration.
Each 380501511 harness is 100% continuity-tested and hi-pot tested at 1.5kV before packaging. A traceable serial number sticker is attached for quality audits. This level of detail guarantees zero defects upon arrival.
Damaged wiring in motor graders often leads to intermittent gauge readings, non-functional warning lights, erratic HVAC behavior, or even CAN bus communication errors. The 380501511 harness resolves all these issues by providing fresh, low-resistance paths for every signal.
This harness integrates connections for the speedometer, tachometer, fuel level sender, coolant temperature sensor, oil pressure switch, parking brake indicator, and transmission control display. It also supplies power to the 12V auxiliary outlets and diagnostic port.
For graders equipped with XCMG’s advanced monitoring system (XMS), the 380501511 harness includes dedicated twisted-pair wires for CAN bus (J1939 protocol). This ensures accurate data transmission without electromagnetic interference.
Construction equipment operates in dust, mud, salt spray, and extreme temperatures. The 380501511 Dashboard Harness is tested to withstand 500 hours of salt spray (ASTM B117) without corrosion. The insulation resists diesel, hydraulic fluid, and battery acid exposure.
Connectors feature integrated silicone seals and wire-to-wire grommets that maintain IP67 protection even under high-pressure washing. The harness passes a 10‑day thermal cycling test from -40°C to +105°C with 20% humidity to 95% humidity, simulating global operating conditions.
Strain reliefs at all connector backshells prevent wire breakage due to constant steering wheel or pedal movement. Every branch is secured with UV-stabilized cable ties and mounting clips in the same positions as the original factory layout.
Replacing an old or fire-damaged dashboard harness is straightforward with the 380501511. Simply remove the instrument cluster, disconnect all modules, unclip the old harness, and route the new one following the original path. All connectors are keyed and color-coded to prevent mis-mating.
A detailed pinout diagram is included in the package (available as a downloadable PDF upon request). Typical installation time for a skilled technician is 2‑3 hours. For fleet managers, stocking this single SKU simplifies spare parts inventory across multiple grader models.
The 380501511 supersedes older part numbers 380501298, 380501402, and 380501477. Always verify your original harness part number, but the new design is backward-compatible with all GR series graders produced after 2008.
XCMG backs every genuine 380501511 Dashboard Harness with a 12‑month unlimited-hour warranty against manufacturing defects. The harness is manufactured in ISO 9001:2015 certified facilities, with inline inspection at each assembly stage.
Random samples from each production batch are subjected to destructive testing: pull force on terminals, salt spray, insulation resistance after flexing, and vibration to 15g. Only batches that pass all criteria are released for sale.
Using counterfeit or non-OEM harnesses risks electrical fires, incorrect gauge readings, and CAN bus errors that can mislead operators. Protect your equipment and personnel by choosing the authentic XCMG 380501511.
The 380501511 Dashboard Harness is stocked in XCMG regional hubs in North America, Europe, Middle East, Africa, and Asia. Standard delivery via air freight takes 3‑7 business days worldwide. For urgent breakdowns, expedited shipping options are available.
