Automobile harness is the main body of automobile circuit network. Without harness, there would be no automobile circuit. harness refers to the copper perforated contact terminals (connectors) and crimped wires and cables, which are then combined with the harness to form a component connecting the circuit.

The harness industry chain includes wire and cable, connector, processing equipment, harness manufacturing and downstream application industries. The harness is widely used in automobiles, home appliances, computers and communication equipment, various electronic instruments and measuring instruments, etc. the body harness connects the whole body and is generally H-shaped.
Automobile cable, also known as low-voltage cable, is different from ordinary household cable. Ordinary household wires are unipolar copper wires with certain hardness. The wires on the car are all multi-core flexible copper wires, some of which are very thin, and some even dozens of flexible copper wires are wrapped in plastic (PVC) insulated pipes, which are very soft and difficult to break.
Common specifications of cables in automobile harness include cables with nominal cross-sectional areas of 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0, 6.0 mm2 (the nominal cross-sectional areas commonly used by Japanese automobiles are 0.5, 0.85, 1.25, 2.0, 2.5, 4.0, 6.0 mm2), Each has an allowable load current value, which is used for conductors of various electrical equipment. Taking the whole vehicle harness as an example, the 0.5 specification line is applicable to instrument lamps, lighting lamps, door lighting, ceiling lamps, etc; 0.75 specification line is applicable to license plate lamps, small front and rear lamps, brake lamps, etc; Lighting, etc; Wires of 1.5 specifications are applicable to headlights, horns, etc. 2.5-4mm2 wires are required for main wires such as generator foundation wire and ground wire. This only applies to ordinary cars, which depends on the maximum load current. For example, the battery ground cable and the positive power cable are special vehicle cables that are used separately. Their wires are relatively large in diameter, at least 10 mm2. At the top, these "Big Mac" wires are not woven in the main harness.
Vehicle electrical harness is the main body of vehicle circuit network. It connects and operates the electrical and electronic components of the vehicle. No wiring harness, no car circuit. Whether it is a high-end luxury car or an economical ordinary car, the harness is basically the same at present, consisting of wires, connectors and packaging belts. It not only ensures the transmission of electrical signals, but also ensures the connection of circuits. To ensure reliability, power shall be supplied to electronic and electrical components according to the specified current value to avoid electromagnetic interference to surrounding circuits and eliminate electrical short circuit.
