What is an automotive wiring harness and what does it do?

Automotive wiring harness is a set of assembly parts consisting of wires, cables, connectors and insulating materials, which are used to connect various electronic and electrical devices of automobiles. Automotive wiring harness can be said to be one of the core components of automotive electrical system. Wiring harnesses play an important role in automobiles because they are responsible for transferring signals and energy between various systems to the right place. This article will explore the role of automotive wiring harness from multiple perspectives. The main function of the wiring harness is to connect the various electrical equipment of the vehicle, such as engine control unit, lighting equipment, electric windows, air conditioning and so on. These devices need to be controlled by circuits, and the automotive wiring harness provides a centralized electrical connection channel to connect these devices with the power supply, control unit and other major components of the vehicle. Because the wires and cables in the harness are insulated, the electrical signals can be effectively protected from external interference, thus ensuring the reliability and stability of the automotive electrical system. The sensor signal transmission automotive wiring harness is not only used to connect the electrical equipment inside the vehicle, but also responsible for transmitting the sensor signal to the vehicle's electrical control system. For example, an oxygen sensor can detect the oxygen content in the exhaust gas and then transmit the detection result to the vehicle's electronic control unit to adjust the fuel injection amount of the engine. The wiring harness may also transmit other sensor signals, such as temperature, humidity, pressure, etc., to monitor vehicle conditions and adjust accordingly. Space-saving automotive wiring harnesses not only connect the various electrical devices inside the vehicle, but also keep them close together, reducing the clutter of wires and cables. The advantage of this is that it can save space, make the interior of the vehicle cleaner, reduce the interference between lines, and improve the stability and reliability of the electrical system. Simplify Maintenance Because automotive wiring harnesses can bring all the wires and cables together, it makes it easier to maintain and overhaul automotive electrical systems. If a wire fails, simply trace the harness to find the line, making repairs or replacements faster. This can reduce the time and effort to find the fault point and improve the maintenance efficiency. 2. What are the main automobile wiring harness factories? What is the function of the car harness? Automotive wiring harness is a collection of multiple wires and connectors used to connect the various electrical devices in the car together to achieve communication and control between them.
