Problems solved by technology

Therefore, the requirements for automotive wiring harnesses are getting higher and higher, and the design of automotive wiring harnesses is becoming more and more complicated under the requirement of adding more lines.
The problem in reality is that the wiring harness is getting bigger and bigger, and it is more difficult to arrange all the wiring harnesses in a limited space. Due to the increase of lines, the reliability requirements for the wiring harness are getting higher and higher.
