In the automotive industry, wire harnesses (also known as cable harnesses) are one of the core components of automotive electrical systems. Its main functions include:

Power transmission: The wiring harness is responsible for transmitting power from batteries, generators, and other power sources to various electronic devices and electrical components of the car, such as lights, sensors, instrument panels, etc.

Signal transmission: In addition to power transmission, wiring harnesses are also responsible for transmitting various signals. These signals may come from the car's control system, sensors, or other electronic components to ensure the coordinated operation of various parts of the vehicle.

Organization and protection: Wiring harnesses organize various cables and wires together to form a structured whole. This organization not only helps reduce cable clutter, but also protects cables from mechanical damage, chemical corrosion, and environmental factors through insulation layers.

Simplified installation: Wiring harnesses are typically composed of multiple cables and connectors, which can simplify installation during the vehicle manufacturing process. A well-designed wiring harness system can effectively reduce wiring time and errors, and improve production efficiency.

Improving reliability: High quality wiring harness design can reduce the risk of electrical system failures, ensuring the reliability and safety of automotive electrical systems.
