Configuration and selection At present, users still focus on the selection of cars, and configure the vehicle according to the choice of comfortable or flagship models, or optional packages. For example, high-end models are equipped with electric folding rearview mirrors and sensor wipers. Although these two functions are different in type and function, they can be guaranteed to be selected at the same time, so the two electrical appliances can also be combined in the same module. This reduces the current cost of managing modules, which can then be taken apart when necessary.
Redundant Cabling Include some branches in certain configurations, whether ordered by the customer or not. For example, this branch is included in the wiring harness part whether or not the customer chooses the front fog lights. This approach is only applicable if the reduced administrative costs are greater than the actual material incremental costs.
