[0002] The end of a vehicle harness is the end portion of a harness in a vehicle's electrical system. A harness is a group of wires, cables, or conduits that transmit power or signals and connect various vehicle components and devices, such as the engine, lighting system, dashboard, sensors, etc. The end of a vehicle harness connects various components and devices in the vehicle's electrical system, and they are usually connected to these components and devices through connectors. The end of a harness can include the bare end of the wire or a connector. These connectors can be in the form of plugs, sockets, terminals, etc., and are used to connect to other harnesses, sensors, switches, etc. The end of a vehicle harness is a vital component of the vehicle's electrical system, and their design and protection are essential to ensure the reliability and safety of the electrical system.
