The automobile wiring harness is the main body of the automobile circuit and the carrier for transmitting electronic signals and power energy. It is mainly composed of wires, terminals, sheaths and other coverings. As the center of information transmission, wiring harness is related to the safety of vehicles and the reliability of electrical and electronic equipment. Automotive wiring harness products are customized products, and vehicle manufacturers and their models have different design schemes and quality standards.

The data shows that although the overall car sales in 2020 will recover strongly after the epidemic, it is expected to continue to grow in the next few years. In 2025, the car sales will exceed 30 million vehicles, the degree of electrification and intelligence will increase, and the proportion of wiring harness prices will increase year by year. It is estimated that by 2025, the wire harness market will reach 130 billion yuan. With the deepening of industry competition, the following main characteristics are presented:

1. The strong cooperation between the wiring harness factory and the vehicle manufacturer has improved the market concentration.

Most OEMs in the automotive industry have their own relatively mature and stable automotive supporting systems. As far as the domestic wiring harness market is concerned, most of the large-scale independent OEMs have stable supporting production of local wiring harness factories, while foreign and joint venture OEMs are mostly wholly-owned or joint ventures by international component manufacturers in China, and they have formed a stable relationship of long-term cooperation. . However, in recent years, as international auto manufacturers pay more and more attention to cost control, the localized procurement of auto parts has been increasingly strengthened, which has brought opportunities to excellent domestic independent wiring harness enterprises. Through the long-term accumulation of product technology and simultaneous development experience, the overall strength of these high-quality local enterprises has been significantly enhanced, and the timely and effective service and reliable product quality have gradually entered the supporting system of international automobile manufacturers.

2. The simultaneous R&D capability of the wiring harness factory is becoming more and more important.

The interface definition of the vehicle wiring harness involves each electronic system, and the principle of the wiring harness is closely related to the electrical principle of the vehicle, so the design of the wiring harness is most closely related to the vehicle manufacturer. In addition, the rise of global procurement of auto parts and the industrial division of labor and cooperation formed by vehicle companies and parts companies make it necessary for automotive wiring harness companies to participate in the design and development of new models. Synchronized development requires automotive wiring harness suppliers to integrate into the vehicle supporting system and fully understand the standards, progress, quality and needs of vehicle design. It must be based on the vehicle manufacturer's plan and time node, in line with the vehicle development progress, and timely launch of automotive wiring harnesses design, validation, production scenarios and final products. Therefore, in order to improve the vehicle supporting ability of automobile wiring harness enterprises, the synchronous research and development strength is particularly important.

3. Independent wiring harness enterprises have a leading position in the field of new energy.

The driving voltage of new energy vehicles is high, and high-voltage wiring harnesses are required to connect each circuit unit. High-voltage wiring harness is not only a key component of the high-voltage electrical system of new energy vehicles, but also an important guarantee for the safe and reliable operation of new energy vehicles. China's local wire harness suppliers are the first to enter the new energy vehicle supply system by virtue of their good supporting relationship with independent new energy vehicle factories. Some high-quality wire harness companies have made technological breakthroughs in the field of high-voltage wire harness design and development, with leading R&D strength and huge development potential.

4. The domestic wire harness leader appears, and mass and lean production has become the commanding heights of competition.

At present, although there are many domestic automobile wiring harness manufacturers, most of them are small in scale, weak in R&D capability, backward in production equipment, low in quality, and single in supporting models. They are mainly processed by independent automobile enterprises. With the improvement of the overall strength of independent brand parts companies, some leading wiring harness companies that have established brand influence in the high-end and high-quality wiring harness market have begun to speed up the layout of industrial capital, integrate industrial resources, and give full play to their partners in technology, customer resources, and supporting services. The synergy in services and other aspects will speed up the survival of the fittest in the industry. For example, Guangdong Wanlian Technology has accumulated 20 years of R&D and production experience, and has built a one-stop service platform for all types of connectors - Electronic Valley. Electronic Valley connector products are mainly original factories, self-owned brands and self-owned factories.

In the future, my country's wiring harness industry will face the survival of the fittest and accelerate the industrial environment of resource integration. Based on production costs and high-quality requirements, high personnel costs, recruitment difficulties and other issues, lean production will become the commanding heights of competition.
