A wire harness is a collection of wires, connectors, and terminals that are bundled together to transmit electrical power and signals. They are commonly used in various applications, including automobiles, electronics, and machinery, to organize and protect electrical connections. By grouping wires together, harnesses help reduce the risk of damage and simplify installation. Wire harnesses can vary in size and complexity, depending on their intended use. For example, in the automotive industry, a vehicle may have multiple wire harnesses connecting components like the engine, lights, and dashboard. This organization ensures efficient operation and easier maintenance of electrical systems.
