Dongfeng xinjiang truck parts Configurable main harness assembly for the body 3727005-C3901-A6

Built for flexibility, this main harness assembly features a configurable structure that accommodates custom body modifications for Dongfeng Xinjiang trucks. It includes 8 modular branch circuits (each with detachable connectors) that can be added, removed, or adjusted to support aftermarket equipment (e.g., refrigeration units, cargo monitoring systems, additional lighting). The harness’s core backbone uses a split-design sleeve, allowing easy access to internal wires for reconfiguration without cutting or splicing the main circuit. Each branch is labeled with clear identifiers (e.g., “Refrigeration Power,” “Cargo Light Signal”) for quick customization. Additionally, the assembly supports voltage options (24V standard, compatible with 12V accessories via optional converters), making it suitable for various body configurations (e.g., flatbed, tank truck, van). This configurability eliminates the need for custom harness fabrication, reducing modification time and costs

Engineered to withstand the tough conditions of truck operations (vibration, moisture, abrasion), the harness assembly features comprehensive protective layers. The outer sheath is made of flame-retardant PVC (UL94 V-0 rating) with a thickness of 1.2mm, resisting oil, grease, and UV radiation—preventing cracking or aging in extreme temperatures (-40℃ to 105℃). Internal wires are insulated with cross-linked polyethylene (XLPE), offering excellent electrical insulation and resistance to thermal degradation. All connectors are IP67-sealed, blocking dust and water intrusion even in muddy or rainy conditions. The harness is also wrapped with abrasion-resistant fabric tape at stress points (e.g., door hinges, frame edges), preventing wire wear from vibration. These protections ensure the harness maintains electrical integrity for over 8 years, reducing downtime from short circuits or connector failures

Designed to deliver consistent signal and power transmission, the harness assembly uses high-conductivity oxygen-free copper (OFC) wires with low resistance (≤0.01Ω/m for 1.0mm² wire). This minimizes voltage drop and signal interference, ensuring reliable operation of body electrical components (e.g., LED headlights, electronic door locks, diagnostic sensors). The wires are twisted in pairs (for signal circuits) to reduce electromagnetic interference (EMI) from the truck’s engine or radio systems, preventing false signals or component malfunctions. Terminal crimps are precision-controlled (crimp force: 80-100N) to ensure tight connections, avoiding intermittent contact from road vibration. Additionally, the harness includes inline fuses and relays (rated for 5-30A) to protect sensitive components from overcurrent, enhancing system safety. This stable transmission guarantees the body electrical system operates flawlessly in long-haul or off-road conditions

Designed for user-friendly installation, the harness assembly features a plug-and-play design with pre-assembled connectors and mounting clips. All connectors are keyed to prevent reverse insertion, and the harness is pre-routed with labeled branches for quick identification of components (e.g., “Front Left Light,” “Rear Door Lock”). The package includes 12 high-strength mounting clips that align with the truck’s body frame holes, securing the harness without drilling. Installation steps are straightforward: disconnect the old harness from the BCM and components, route the new harness along the factory path, plug in all connectors until they lock into place, and secure with the included clips. A professional technician can complete installation in 90 minutes or less, avoiding time-consuming wire splicing or configuration. For repair shops or truck operators, this easy installation design reduces labor costs and minimizes truck downtime—critical for commercial operations
