Dongfeng xinjiang X7 truck parts Right headlight harness 3724215-TXGG01Y

Built to support the complete functionality of the Dongfeng Xinjiang X7’s right headlight, this harness delivers stable power and signal transmission for all lighting modes. It includes dedicated circuits for high beam (12V/55W), low beam (12V/55W), daytime running light (DRL, 12V/10W), turn signal (12V/21W), and position light (12V/5W)—each with color-coded wires (e.g., red for power, yellow for turn signal) for easy identification. The harness also integrates a dedicated ground wire (2.5mm²) with a corrosion-resistant terminal, ensuring reliable electrical grounding and preventing voltage fluctuations that could damage the headlight’s LED or halogen bulbs. Unlike basic harnesses that only support partial functions, this unit enables the X7’s right headlight to operate in all factory-designed modes, maintaining optimal visibility and safety for night driving or adverse weather

Engineered to withstand the harsh conditions of the truck’s front end—including moisture, road debris, temperature changes, and vibration—the harness 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 abrasion from rocks or road salt. Internal wires are insulated with cross-linked polyethylene (XLPE), offering excellent electrical insulation and thermal stability (operating temperature range: -40℃ to 105℃). All connectors are IP67-sealed, blocking dust and water intrusion even in heavy rain or muddy driving. The harness is also wrapped with abrasion-resistant fabric tape at stress points (e.g., near the front bumper, where the harness bends) to prevent wire wear from vibration. These protections ensure the harness maintains electrical integrity for over 7 years, reducing downtime from short circuits or connector failures

Designed to deliver consistent signal and power for the right headlight, the harness uses high-quality materials to minimize interference and voltage drop. The power wires are made of high-conductivity oxygen-free copper (OFC) with low resistance (≤0.01Ω/m for 1.5mm² wire), ensuring the headlight receives full voltage (12V±0.5V) for bright, stable illumination. Signal wires (for turn signal and DRL) are twisted in pairs (twist rate: 12 twists/m) to reduce electromagnetic interference (EMI) from the truck’s engine or radio system, preventing false signals that could cause the turn signal to flicker or the DRL to malfunction. Terminal crimps are precision-controlled (crimp force: 90-110N) to ensure tight connections, avoiding intermittent contact from road vibration. Additionally, the harness includes inline fuses (15A for power circuits) to protect the headlight and BCM from overcurrent, enhancing system safety

Designed for efficient installation on the Dongfeng Xinjiang X7, the harness 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 segments (e.g., “Headlight Connector,” “BCM Connector”) that match the X7’s front-end wire routing channels. The package includes 8 high-strength plastic mounting clips (compatible with the X7’s front frame pre-drilled holes) and a detailed installation guide with X7-specific diagrams. Installation steps are straightforward: route the harness along the X7’s front frame, secure it with clips, plug the connectors into the right headlight and BCM, and test for function. No specialized tools (e.g., wire strippers or crimpers) are required, and a professional technician can complete installation in 40 minutes or less. This easy installation design reduces labor costs and minimizes truck downtime—critical for commercial operations relying on the X7’s front lighting for safety
