What knowledge should automotive wiring harness engineers possess?

Automotive wiring harness engineers must have the following points.

The control schematic diagram can be understood as: because the wiring harness of automobile air conditioner is designed according to the schematic diagram.

Principle of every electrical product: Because automotive wiring harness connection is every electrical product, you must know the pin definition of every electrical product, and you will also know about electrical products.

Connectors: There are many connectors used in automotive wiring harness, and there are also many connector manufacturers. There are Yaqi, Ampu, Hu Lian, KET, KUM and so on abroad. Domestic THB, Yuyao, Nantong Youxing, Zhejiang Zhao Jin, etc.

Conductor: The wire harness must have conductors, and there are many kinds of conductors, such as domestic QVR, German FLRY, Japanese AVS, AVSS, American AWG, etc. There are also many kinds of wire diameters, 0.5mm? ， 1.0mm？ Wait, every current that can pass is different, and we have to consider the color of the wire.

Big picture: Where is the branch point of the harness? Pick up what? How long is the wire? Cost should also be considered.

Of course, it also includes many small details. How are small products, including clips and labels, protected? Insulating tape? Velvet tape?

The main work of automotive wiring harness engineer:

Automotive wiring harness engineer is responsible for wiring inside and outside the car, such as wiring harness design from automobile ECU to front and rear lights, wiring harness design from sensors in engine and chassis to respective ECU, and wiring harness design from control panel to ECU.

There is no such position in the maintenance industry, but in a large automobile assembly workshop. It is responsible for the design and installation of the main wiring harness.
