A wire harness is a collection of wires, connectors, and terminals that are bundled together to transmit electrical power and signals. It is commonly used in various applications, including automobiles, electronics, and machinery, to organize and protect electrical connections. By grouping wires, a wire harness simplifies installation and reduces the risk of damage. Wire harnesses can be customized to fit specific needs, ensuring that the right length and type of wire are used for each application. They help improve reliability and efficiency by minimizing the chances of short circuits and other electrical issues. Properly designed wire harnesses contribute to the overall safety and functionality of devices and systems.
