With the rapid development of automobile technology and the gradual improvement of automobile automation and intelligence, people’s requirements for the safety, comfort and entertainment of automobiles are also constantly improving. With the continuous increase of equipment, the whole vehicle wiring harness, which is used as a “neural network” to connect various electrical equipment of the automobile, is also becoming more and more complex, and higher requirements for reliability are also put forward.

In recent years, the fierce competition in the automobile market has intensified. Many car companies have introduced competition measures at various levels. In fact, market competition is ultimately a competition in technology, price, service, and quality and reliability.
Among them, technological competition is the core competition, and good technology determines whether car companies can win the top spot. The competition between quality and reliability determines whether car companies can survive.
