First, the electrical layout engineer will first provide the functions, electrical loads and related special requirements of the vehicle's electrical system. The state of the electrical device, the installation position, and the form of the harness connected to the electrical device.

Second, according to the electrical functions and requirements provided by the electrical layout engineer, you can draw the electrical schematic diagram and circuit diagram of the entire vehicle.

Third, according to the electrical principle circle, distribute energy to each electrical subsystem and circuit, including the ground wire of the power supply and the distribution of the grounding point.

Fourth, according to the distribution of the electrical parts of each subsystem, determine the wiring form of the harness, the electrical components connected to each harness and the direction of the car; determine the external protection form of the harness and the protection of the vias; determine the fuse according to the electrical load Or circuit breaker; then determine the wire diameter of the wire according to the amount of fuse or circuit breaker; determine the wire color of the wire according to the function of the electrical device and according to the relevant standards; determine the terminal and protection of the wire harness and its docking according to the connector of the electrical device itself Set model.

Fifth, draw a two-dimensional wiring harness diagram and a three-dimensional wiring harness layout diagram.

Sixth, according to the approved three-dimensional wiring harness layout diagram, check the two-dimensional wiring harness diagram, the two-dimensional wiring harness diagram must be accurate before the drawing can be issued, and after approval, the prototype can be produced and produced according to the wiring harness diagram.

The above six major processes are too general. The specific process of automotive wiring harness design will encounter many such problems, all of which need to be analyzed calmly by the harness designer to ensure the rationality and reliability of the harness design and ensure the integrity. Car circuit design went smoothly.
