A wiring harness is a collection of wires, connectors, and terminals that transmit electrical power and signals within a device or vehicle. It organizes and protects the wires, ensuring they function properly while minimizing the risk of damage. Wiring harnesses are commonly used in various applications, including automobiles, aircraft, and household appliances. These harnesses are designed to simplify the assembly process and improve reliability. By grouping wires together, they reduce clutter and make troubleshooting easier. Automotive manufacturers often rely on wiring harnesses to connect components like sensors, lights, and motors, enhancing overall efficiency and safety.
