If you have a vehicle project that requires a custom wiring harness, call the team at Kinkong customization harnesses. For example, rather than individually installing each wire, cable, and subassembly, the saddle consolidates them into a single unit for the OEM or installer to handle. Caption: Multicolor wires packed in automotive. Once a design is finalized, the first step in making a wire harness is drawing out a schematic that will be necessary for documentation and assembly board. As a result, the wires will be safe from any potential electrical damage, whether inside or outside. Another mistake that engineers make is lack of standardization in the design criterion. Pre-design measurements should include: Wire ends which includes strip lengths, type of terminal, coating of terminal and end, connection points, connector design. Others will face pressure.
