Original Dongfeng VR Bumper harness assembly 3724200-C1118

As a fully integrated assembly, this harness is pre-configured to support all electrical functions of the Dongfeng VR bumper. It includes dedicated wires for fog lamps (power and ground lines), turn signal lamps (signal transmission lines), parking sensors (data and power lines, if applicable), and backup lamps (if integrated into the bumper). Each wire is color-coded according to Dongfeng’s OE standards (e.g., red for power, black for ground, yellow for turn signals), allowing for quick identification during installation and maintenance. The harness also features pre-crimped terminals and pre-assembled connectors (e.g., waterproof blade connectors, socket connectors) that directly mate with the bumper’s electrical components and the truck’s main wiring harness. This complete integration eliminates the need for on-site wire cutting, crimping, or splicing, reducing installation time by 60% compared to building a custom harness and minimizing the risk of wiring errors

The harness assembly is equipped with comprehensive protective features to withstand the harsh conditions of bumper-mounted use (exposure to rain, mud, road salt, vibration, and temperature fluctuations). The wires are insulated with high-temperature-resistant PVC sheathing (capable of withstanding -40°C to 125°C) that resists cracking, aging, and chemical corrosion from oil, grease, and road deicers. The entire harness is wrapped in a durable braided polyester sleeve or corrugated nylon tube, providing additional protection against mechanical abrasion (e.g., contact with bumper components or road debris) and impact damage. Critical connection points and terminals are sealed with waterproof silicone gaskets and heat-shrinkable tubing, meeting IP67 waterproof standards to prevent water intrusion and short circuits. These protective measures extend the harness’s service life to 5+ years under normal heavy-duty operation

To ensure reliable electrical signal transmission and power supply, the harness uses high-purity copper wires (with a cross-sectional area of [add specific data if available, e.g., 0.5-1.0 mm²] depending on function) that offer low electrical resistance (≤0.018Ω/m at 20°C). This ensures stable power delivery to bumper components (e.g., fog lamps) and accurate signal transmission for sensors or turn signals, preventing issues like dim lights, intermittent signal loss, or sensor malfunctions. Additionally, the harness is designed with anti-interference measures: power wires and signal wires are separated by insulating barriers, and critical signal lines (e.g., parking sensor data lines) are shielded with aluminum foil or braided copper shielding to reduce electromagnetic interference (EMI) from the truck’s engine or other electrical systems. This guarantees consistent performance even in high-electromagnetic environments

Designed for user-friendly installation, the harness assembly comes with pre-attached fixing clips, cable ties, and mounting brackets that match the Dongfeng VR bumper’s original attachment points. These fixing elements allow installers to securely route the harness along the bumper’s inner structure without additional drilling or adhesive, ensuring proper wire management and preventing movement (which could cause abrasion or terminal disconnection) during truck operation. The harness also features a single main connector that plugs directly into the truck’s main wiring harness—enabling "plug-and-play" installation. No specialized electrical tools or programming are required: installers only need to route the harness, secure it with the included clips, connect the component terminals (fog lamps, signals, etc.), and plug in the main connector. The entire process can be completed in 40-60 minutes by a single mechanic, significantly reducing maintenance time and labor costs
