• From a functional point of view, automotive wiring harnesses are divided into two types: power lines, which carry the power of the actuators (actuators), and signal lines, which transmit the input commands of the sensors. Power lines are thick wires that carry high currents, while signal lines are thin wires that do
  not carry electricity (optical fibre communication); for example, the cross-sectional area of wires used for signal circuits is 0.3 or 0.5 mm².

• The first station in the production of wire harnesses is the open wire process. The accuracy of the open wire process is directly related to the entire production schedule, once the error is made, especially the open wire size is short, it will lead to rework of all stations, which is time consuming and affects production efficiency. So in the preparation of the open wire process is to be based on the requirements of the drawings to determine the reasonable size of the wire open wire, stripping head size.

• The final step is the assembly process. According to the product development department's design of the assembly table, the design of the assembly equipment, material box specifications and the size of all the assembly sheaths and accessories numbered on the material box to improve the efficiency of the assembly. Prepare the assembly content and requirements for each workstation and balance the entire assembly workstation to prevent too much work at one point and pulling down the speed of the entire assembly line. To achieve a balanced workstation, the process personnel must be familiar with each operation and measure the working hours on site to adjust the assembly process at any time.

• In addition, the wiring harness process also includes the preparation of material consumption quota schedule, work time measurement, worker training, etc., due to the value of technical content is not high, these will not be detailed. All in all, automotive wiring harnesses in the car electronic technology content and quality, and gradually become an important indicator to evaluate the
  performance of the car. Automotive manufacturers should pay particular attention to the selection of wiring harnesses, it is also necessary to understand the process and production of automotive wiring harnesses.

• The number of circuits and the amount of electricity used in a car increases significantly, and the harnesses become thicker and heavier as the functions of the car increase and electronic control technology is commonly used. This is a major problem that needs to be solved. How to make a large number of wire harnesses in the limited space of the car how to more effectively and reasonably arranged, so that the car harnesses play a greater function, has become a problem facing the automotive industry.
