The automotive wiring harness is the main body of the network of the automobile circuit, connecting the electrical and electronic components of the car and making it function, without the wiring harness there is no automotive circuit. At present, whether it is a high-end luxury car or an economical ordinary car, the form of wire harness is basically the same, which is composed of wires, plug-ins and wrapping tape, which must not only ensure the transmission of electrical signals, but also ensure the reliability of the connected circuit, supply the specified current value to the electronic and electrical components, prevent electromagnetic interference to the surrounding circuit, and eliminate electrical short circuits.
Automotive wiring harnesses are divided into two functions: power lines that carry power to drive actuators and signal lines that transmit sensor input commands
