Introduction
Wiring harness is one the most essential parts of the vehicle industry. A wiring harness is an organized set of wires, terminals and connectors that run throughout the entire vehicle and transmit information and electric power, thereby playing a critical role in “connecting” a variety of components. Power and information travel through this network much like the circulatory and central nervous systems of the human body. It conducts electricity for all electrical loads on a vehicle.
Selection of components
Selection of connectors, fuses, lights, switches, sensors, wires, cables, relays, protection tubes, motors etc. are the core components of the wiring harness. The performance of these components directly determines the overall performance of the wiring harness and plays a decisive role in the stability and safety of the whole vehicle. The basis of the selection of these components is the voltage system and its current carrying capacity. Ambient temperature in the selection of these components is one of the most important aspects of wiring harness design. Proper selection of these electrical components and their conductors ensures reliability and safety. For example, for the requirements of high performance airbags like ABS and ECU with a terminal connector, gold-plated pieces are preferred to ensure safety and reliability.
Wiring Diagram
Wiring diagrams are also known as schematics or circuit diagrams. The selected components are placed and connected to each other in the diagram. These components belong to a set of libraries which can be modified and configured according to customer specific requirements. A wiring diagram shows each connection in detail. The schematics give an overview of the components that are part of the electrical design. Other items in the schematics are for example cables, sheet cross references and ECUs.
If an assembly is going to be used for communications or data signal transmission, twisted pairs should be considered to eliminate the risk of noise or EMI (electromagnetic interference) impacting on the performance of the assembly.
