A custom aircraft wiring harness is a crucial component of an aircraft's electrical systems. The aeroplane wire harness is created through aircraft wire harness fabrication, which involves fabrication, assembly, and testing. Custom aircraft wiring harness uses thick and durable wires to reduce weight, and they employ materials such as copper and silver-plated copper. The harness also features custom connectors and amperage limits are built into the design to ensure each component gets the proper amount of power. The design of the custom wiring harness is done to ensure the longevity of the electrical components, and it is also optimized for flexibility.
