Inform of the requirements.

We accept CAD drawings or physical samples to begin the customization process. If drawings are not available, customers may work with a local engineer to create them before sharing with us. Additionally, please provide detailed requirements including wiring layout, functionality, harness length, structure, terminal types, wire specifications, and connection methods. Our design process also incorporates critical factors such as maintainability, waterproof performance, and EMI resistance to ensure reliability.
