Replace old products with new products with lower cost and better performance, and replace foreign products with domestic products with lower price and similar performance. However, in the long run, effective substitution is the best way to reduce the production cost of wire harness. Refinement and optimization of the design process. To understand the electrical principle of the vehicle, a reasonable vehicle wiring harnesses division. If the wire harness design is detailed to the line design, take full account of the use of each wire, wire warp, length and so on. These problems are considered, the design of the line is difficult to be uneconomical.

Product versatility and continuity: simply speaking, in the early design stage, try to take mature models of the same platform as the reference, which can not only reduce the development cycle of the whole vehicle wiring harness, reduce the procurement cycle of new parts for new projects, and reduce the cost of mold opening. 3D wiring harness design. Now we are in the process of design, from the source of control, electronic loading. In this way, the problem of interference between wire harness and plate metal is avoided in the design stage, and the reasonable direction branch is solved so as to effectively control the line length. In this way, a lot of later rework is avoided, and the cost is also virtually saved.
