Part No.: 252102885
Applicable Model: XCMG ZL50G, ZL50GL Wheel Loader
Type: Cab control box area wiring harness assembly
Installation Position: Cab control box area
Function: Signal transmission and power connection for switches, solenoid coils, and electrical components in the control box

Applicable Scenarios

Widely used in quarry, aggregate yard, and earthwork construction sites with obvious vibration and heavy dust. It is a key wiring harness accessory for ensuring stable control signal transmission and normal control functions.

▪ Manufactured to OEM routing layout for good installation fit
Harness routing, length, and connector positions are designed to ZL50G/ZL50GL control box electrical interfaces, requiring no original layout modification during replacement and shortening on-site repair time.

▪ Insulation provides wear, oil, and aging resistance
Harness insulation provides certain protection against cab interior oil and machine vibration, suitable for long-term loader use.

▪ Connector specifications match original control components
Connectors are manufactured to original control valve solenoid coil, switch, and other component specifications for good mating fit, reducing control failure from poor contact.

▪ Can be purchased separately from same-series harnesses to reduce mismatch
Same-series harnesses include front frame harness 252101988, instrument panel harness 252101989, etc.; distinguish by position when purchasing.

FAQ 

Q：Is control function abnormality always caused by the harness?
A: Not necessarily. Check corresponding fuses, solenoid coils, switches, and connectors first. Inspect the harness for open circuits, shorts, or insulation damage after confirming peripheral components are normal.

Q：Can the harness be partially repaired?
A: Minor insulation damage can be temporarily treated with insulating tape or heat shrink tubing. Loose connectors can be re-crimped or terminals replaced. If the harness has multiple internal breaks or large-area damage, replacing the entire harness is recommended.

Q：What to note during control box harness installation?
A: Confirm the harness model matches the vehicle configuration and disconnect power before installation. Route the harness along the original path, avoiding contact with sharp edges and high-temperature components. Insert connectors fully with locks engaged after alignment.

Q：How to maintain the control box harness daily?
A: Regularly check harness insulation for damage and connectors for looseness and corrosion. Avoid liquid entering connectors during cleaning. Check harness fixing clips during electrical system maintenance.
