A wire harness (circuit group) is the overall collection of service equipment provided for a certain load source group, such as trunk lines, switching devices, control systems, etc. The basic research content of traffic theory is to study the relationship among traffic volume, call loss, and wire harness capacity. Therefore, a wire harness is an important basic concept in traffic theory.

　　For ease of installation and maintenance, and to ensure electrical equipment can operate under the harshest conditions, wires of different specifications and colors used in various electrical equipment throughout the vehicle are combined into a single unit through reasonable arrangement, and bundled together with insulating material, making it complete and reliable.

　　2. Proper selection of wire cross-sectional area and color code

　　1) Correct selection of wire cross-sectional area

　　Electrical equipment in the vehicle selects the cross-sectional area of the wire used based on the size of the load current. For electrical equipment working for a long time, 60% of the actual current carrying capacity of the wire can be chosen; for electrical equipment working for a short time, 60%-100% of the actual current carrying capacity of the wire can be used.

　　2) Selection of wire color code

　　For ease of identification and maintenance, wires in the wire harness use different colors.

　　For convenience in marking on circuit diagrams, the colors of the wires are all represented by letters, and the colors they represent are annotated in each circuit diagram.
