The 380501513 Control Box Harness is a genuine OEM wiring assembly manufactured by XCMG for motor graders and heavy construction equipment. This complete harness connects the operator control box to the main cab wiring, vehicle ECU, and chassis systems, enabling reliable transmission of control signals and power.
Engineered to withstand extreme vibration, temperature fluctuations, and chemical exposure, the 380501513 harness uses cross-linked polyethylene insulation and tinned copper conductors. It directly replaces damaged or corroded control box wiring in XCMG GR series graders and compatible machinery.
Each assembly is pre-terminated with original XCMG connectors and includes all necessary branch leads for switches, indicator lights, potentiometers, and the hour meter. Plug-and-play installation restores full control box functionality, including lighting controls, all-wheel drive switching, and filter monitoring systems.

The XCMG 380501513 Control Box Harness is the central nervous system of the operator’s control interface. It carries signals from every switch and potentiometer in the control box to the main ECU, transmission controller, and lighting modules. A damaged harness can cause intermittent failures, erratic lighting, or complete loss of control functions.
XCMG designs this harness to match the exact original routing and connector locations. Every branch length is precisely measured to reach each control box component without tension or slack. The harness includes dedicated circuits for the wide light switch, headlight switch, front and rear working lights, circumference lamp, and extreme signal lamp.
The 380501513 also integrates wiring for the all-wheel drive switching system, hot-blast heating controls, page turning switch, gear switch, multiple filter indicator lights, potentiometer, hour meter, and radio cassette player. Replacing a degraded harness restores full functionality and prevents electrical fires.
All connectors on the 380501513 harness are genuine XCMG-sourced components, identical to those used in the original factory assembly. The main 24-pin connector uses sealed Deutsch-style terminals with secondary locking features to prevent pin push-out. Each terminal is crimped using XCMG-approved tooling, ensuring contact resistance below 10 mΩ.
The harness also includes multiple 12-pin auxiliary connectors for expansion modules, as well as individual 2-pin, 3-pin, and 4-pin sealed connectors for switches and indicator lights. All connectors feature integrated silicone seals that maintain IP67 protection even under high-pressure washing.
Terminal retention force exceeds 50 N per pin, and the housing is made of UL94 V-0 flame-retardant material. The 380501513 harness is 100% continuity-tested and hi-pot tested at 1.5 kV before packaging, ensuring zero defects upon arrival.
The 380501513 Control Box Harness is manufactured by XCMG’s certified wiring harness facility, which produces over 150,000 wire harness sets annually for construction and commercial vehicles. The facility operates under IATF 16949 (automotive quality management) and ISO 9001:2015 certifications, ensuring consistent quality.
Each harness is tested to withstand 500 hours of salt spray (ASTM B117) without corrosion, 100 thermal shock cycles from -40°C to +125°C, and 20g vibration for 24 hours across 10-2000Hz. The XLPE insulation resists diesel, hydraulic fluid, and battery acid exposure, preventing premature cracking or short circuits.
Corrugated conduit protects high-wear sections where the harness passes through the firewall or around moving parts. Heat-shrink tubing seals all branch points and provides additional strain relief. The harness is bundled with UV-stabilized cable ties in the same locations as the original factory assembly.
Replacing a damaged control box harness is straightforward with the 380501513. First, disconnect the battery and remove the control box panel. Document wire routing with photos if needed. Unplug all connectors from switches, indicator lights, and the ECU. Remove the old harness and route the new one following the original path.
All connectors are keyed and color-coded to prevent mis-mating. The 380501513 includes integrated wire labels for positive identification. Typical installation time for a skilled technician is 1-2 hours. Reconnect the battery and test all control box functions: lights, heater, all-wheel drive, gauges, and radio.
The 380501513 supersedes older part numbers 380501401, 380501278, and 380501445. Always verify your existing harness configuration, but the 380501513 is backward-compatible with all GR series graders produced after 2010.
Aftermarket control box harnesses often use lower-gauge wire (e.g., 0.35 mm² vs. OEM 0.5 mm²), leading to voltage drop and overheating. The genuine XCMG harness uses tinned copper conductors that meet or exceed original specifications, ensuring reliable signal transmission and power delivery over the life of the machine.
Counterfeit harnesses may also omit protective conduit or use inferior PVC insulation that becomes brittle in cold temperatures, cracking and causing short circuits. The 380501513 uses XLPE insulation rated for -40°C operation, maintaining flexibility even in arctic conditions.
XCMG provides a 12-month unlimited-hour warranty against manufacturing defects. Each harness is serialized for traceability. Protect your equipment and operator safety by choosing genuine XCMG components.
Common symptoms of a failing 380501513 harness include: intermittent switch operation, flickering lights, non-responsive indicator lamps, erratic gauge readings, or complete loss of control box power. Inspect the harness for chafed insulation, corroded terminals, or melted wires near high-current circuits.
If you notice any of these signs, replace the harness immediately. Continuing to operate with a damaged harness can cause electrical fires, damage to the ECU, or unexpected machine behavior. Preventive replacement every 8,000 operating hours is recommended for graders in extreme applications (mining, snow removal, coastal environments).
The 380501513 is a low-cost component relative to the value it protects. A single harness failure can disable an entire grader, costing thousands in downtime. Stock spare harnesses for quick turnaround.
