Dongfeng Kinland truck parts Front wall harness assembly 3724100-C4314

Built as the “nerve system” of the truck’s front-end electrical components, this harness assembly features high-purity oxygen-free copper (OFC) conductors for exceptional conductivity. Each wire has a cross-sectional area of 0.5-4.0mm² (matched to load requirements), achieving a conductivity of ≥98% IACS and a voltage drop of ≤0.1V/m—ensuring stable power supply to high-current components like headlights (10A) and windshield wipers (8A). The conductors are twisted in pairs (twist pitch 10-20mm) to reduce electromagnetic interference (EMI) by 60%, preventing signal distortion in the instrument cluster and ECU. For Dongfeng Kinland’s complex electrical system, this stability avoids malfunctions such as flickering lights or incorrect sensor readings

Engineered to endure the harsh environment of the truck’s front wall (exposed to vibration, moisture, and road debris), the 3724100-C4314 harness adopts a multi-layer protective structure. The wires are insulated with flame-retardant PVC (UL94 V-0 grade) with a thickness of 0.8-1.2mm, resisting oil, diesel fuel, and chemical cleaning agents. The entire harness is wrapped in a braided polyester sleeve (density 16×16 strands/cm²) for abrasion resistance, preventing wire damage from friction with metal brackets. Connector seals use HNBR rubber (IP67 protection) to block water and dust, while terminal pins are tin-plated (5μm thickness) to resist corrosion—passing 1000-hour neutral salt spray testing (ASTM B117) with no contact resistance increase

Optimized for efficient installation and long-term reliability, the harness assembly features precision routing and secure fixing design. It is pre-formed to match the contour of Dongfeng Kinland’s front wall, with 12 integrated nylon mounting clips (PA66 material) that snap into the chassis’s pre-drilled holes—eliminating the need for additional fasteners. The clip spacing (300-400mm) is calibrated to prevent harness sagging and vibration-induced movement (≤3mm displacement at 60km/h). Critical wire junctions are sealed with heat-shrinkable tubes (adhesive-lined, operating temperature -40℃ to 125℃) to prevent water ingress, while branch connectors are labeled with clear identifiers (e.g., “Headlight-L,” “Wiper-Motor”) for quick installation and troubleshooting

This front wall harness assembly ensures seamless system compatibility and significant cost savings for fleet operators. Its OE design guarantees full integration with Dongfeng Kinland’s electrical system, avoiding mismatched connectors that cause short circuits (repair costs up to $1,200) and ECU damage (costing $3,000+). The high-quality materials and protective structure extend service life to ≥300,000km—three times that of aftermarket harnesses—reducing replacement frequency. The pre-labeled and pre-formed design cuts installation time by 70% (a single technician can complete replacement in 1.5 hours), lowering labor costs. By preventing electrical malfunctions, it avoids unplanned downtime (costing $800+ per hour for long-haul fleets). Backed by a 2-year/200,000km Dongfeng warranty, it provides reliable electrical connection and predictable maintenance expenses
