I. Product Features
Integrated wiring：This automotive wiring harness adopts a modular design consisting of a main harness and branch harnesses, integrating interfaces for multiple systems including lighting, rearview camera, brake signal, and combination switch. This greatly reduces the complexity of overall vehicle wiring, resulting in a cleaner and more organized electrical layout.
High-reliability protection：Key nodes of the wiring harness are equipped with double insulation protection using corrugated tubing + heat‑shrink tubing. The main harness nodes are protected by corrugated tubing, and branch nodes are sealed with heat‑shrink tubing. It adapts to a wide operating temperature range of **–40℃ ~ 125℃**, meets **IP67** waterproof and dustproof requirements, and can withstand complex automotive working conditions.
Precise signal transmission：Adopts multi-strand copper core conductors with wire sizes ranging from **0.5mm² to 4.0mm²**, equipped with plug-in waterproof connectors (contact resistance ＜ 20mΩ), ensuring stable current and signal transmission, and reducing electromagnetic interference to sensitive signals such as rearview camera and sensors.
Easy Installation and Maintenance：The harness mounting points are precisely matched to the vehicle body sheet metal holes, using clips and cable ties for installation without additional drilling. Conductors and connectors are doubly marked with wire number tubes and labels (such as codes A/HT1, X/HT17), allowing quick location and troubleshooting during maintenance.
Safety & Compliance Design：The flame retardant rating of the conductors reaches **VW-1**, complying with **QC/T 29106 *Technical Specifications for Low-Voltage Wiring Harnesses for Automobiles***. The grounding design is optimized to effectively reduce fire risks and electromagnetic interference, improving the safety and reliability of the entire vehicle electrical system.
