Description

Technical Field

[0001] The utility model relates to the technical field of automobile wiring harnesses, in particular to an automobile instrument wiring harness assembly. Background Art

[0002] The instrument harness is a key component of the automotive electrical system. It connects various instruments, indicators and controllers. Its main function is to transmit the electrical signals of various vehicle systems to the display screen and indicators on the dashboard, as well as the control switches that the driver can operate. Through this information, the driver can understand the status of the vehicle in real time, including important information such as speed, fuel level, engine temperature, etc.

[0003] The instrument harness is also responsible for transmitting information about the status of the airbags and seat belts. If there is a problem with the airbag or seat belt, the driver will be alerted and prompted to take necessary actions to ensure driving safety.

[0004] Instrument wiring harness is not only about information transmission and warning function, it can also significantly improve the driving experience.
