The Specific Process Of Vehicle Wiring Harness Design Involves The Following Steps

First, the electrical system engineer provides the functions of the entire electrical system, including the electrical load and related unique requirements. The state of the electrical equipment, the installation location, and the form of connection between the wiring harness and the electrical equipment are all key considerations
From the electrical functions and requirements provided by the electrical system engineer, the complete vehicle electrical schematic is created by adding components required for a function and connecting them together. The functions which are commonly used across multiple vehicles in an architecture platform are stored together.
After the schematic is defined, the wiring harness design is created. In one platform, the end customers can have a variety of requirements. It is very time-consuming and expensive if different designs are created for each end user's requirements separately. So, the designer takes care of the multiple variants while designing the wiring harness.
At the end, a 2D representation of all the wiring designs is created to show the way different wires are bundled and how the bundles are covered to secure the wires. End connectors are also shown in this 2D diagram.
These designs can interact with 3D tools for the import and export of details. The wire lengths can be imported from the 3D tool and the end-to-end connection details are exported from the wiring harness tool to a 3D tool. The 3D tool uses these data to add passive components such as straps, cable ties, cable lacing, sleeves, electrical tape, and conduits in relevant locations and send them back to the wiring harness tool.
