A List of Well-known Chinese Automotive Wiring Harness Enterprises (2024)

Automotive wiring harnesses are the network main body of automotive circuits and are the connecting components of automotive electrical systems. Wire harness refers to the contact terminal (connector) made of copper stamping and the wire and cable crimped, and then the external insulator or external metal shell is added, and the wire harness is bundled with a wire harness to form a connecting circuit. The operating conditions and parameters of the car are intuitively reflected on the on-board computer through the wiring harness, which can be said to be the nervous system of a car, so it has always been called the "blood vessel" of the car. The electronic technology content of automobile wiring harnesses has gradually become an important indicator for evaluating automobile performance.

The increase or decrease of the automotive wiring harness market often increases or decreases with the increase or decrease of automobile sales. The two major Japanese automotive wiring harness manufacturers, Yazaki and Sumitomo Wiring Systems, have a combined market share of more than 50%In addition, with Fujikura and Furukawa Electric, Japanese wiring harness companies occupy more than 60% of the market share; In addition, the three South Korean wiring harness companies, Kyungshin, Yura, and Youjin, occupy nearly 15% of the share; The remaining market share is occupied by LEONI, Aptiv, Lear, PKC, Kromberg & Schubert, Coroplast, Draexlmaier, etc. in Europe and the United States.

With the availability of high-quality automotive connectors, the technical barrier to entry for automotive wiring harnesses has been lowered. In the past, although there were many domestic automobile wiring harness manufacturers, most of them were small in scale, backward in production equipment, low quality grade, and single supporting models, most of which were still supporting some independent brands. However, in recent years, domestic wiring harness manufacturers have developed rapidly, quality and reputation have also improved rapidly, and production equipment has become more and more advanced, and many have surpassed foreign wiring harness manufacturers, such as Kunshan Huguang's "unmanned factory".

With the rapid development of China's automobile industry, the automotive wiring harness industry has also grown and expanded, experiencing a spiral development process from scratch, from small to large, from birth, growth to maturity. Based on the market of their own brands, domestic wiring harness manufacturers have also quickly seized the wiring harness market of many joint venture brands. Among them, the better ones include Kunshan Huguang, Tianhai Group, Changchun Light Bulb Factory, Nantong Dadi, Yingkou Abe, Yilian Technology, Jinting Wiring Harness, Luxshare Precision, etc.

For some relatively large independent brands, such as BYD, Great Wall, and Geely, they have their own wiring harness factories specially produced, such as Great Wall Motor's automotive wiring harnesses are mainly provided by its subsidiary Mande Electric, and BYD is operated by Fudi Technology and Fudi PowerSupply automotive wiring harnesses, and Geely Automobile has Geely Gouda automotive electrical appliances.

The reason why the automotive wiring harness market presents such a pattern is because automotive wiring harness manufacturers have their own particularities, first of all, they must have cable production experience and cable cost control. Yazaki, Sumitomo, Lenny, Furukawa, Fujikura, Corop, and Comba are all manufacturers that started with wires and cables. At the same time, most of these manufacturers have upstream mining resources to cooperate, and Sumitomo and Furukawa have their own copper mines, and the cost control is relatively good. Traditional auto parts manufacturers do not have many advantages in the field of wire harnesses, so Valeo sold the wire harness business to Lenny. The second is to have automotive-grade connector technical capabilities, Aptiv and Fujikura are very good manufacturers of connector technology, and Yazaki and Sumitomo also have strong technical strength. Once again, it is very good to cooperate with the vehicle manufacturer, and the wiring harness is very decisive for quality stability, and once the manufacturer is determined, it is difficult to change the supplier. At the same time, the design of the wiring harness involves many factors such as electronics, machinery, heat distribution, etc., and must cooperate with the design of the vehicle manufacturer, and it is difficult for small manufacturers to enter this level of supply chain. The wiring harness also needs to be continuously improved after experimentation. Aptiv and Lear have continued to grow by relying on their supporting relationships with automakers for many years.

The automotive wiring harness processing industry has its own industry characteristics, and domestic wiring harness processing enterprises can only survive in the future market competition by grasping the characteristics of the industry, seeking benefits and avoiding disadvantages, leveraging strengths and avoiding weaknesses, and giving full play to their own advantages.
