What is a wiring harness assembly? What is an electronic wiring harness?

Wiring Harness Assembly (WHA) is the combination of multiple wires, cables, connectors, etc. to form a complete electrical system for electrical connection and signal transmission in automobiles, mechanical equipment, electronic devices, etc. The wiring harness assembly acts as a bridge to connect the various electronic components to ensure the proper transmission of electrical signals, while providing mechanical support and protection.
A wiring harness assembly consists of multiple wires or cables combined by braiding, tying and sheathing to form a monolithic structure. It typically includes the following components:
Wires/Cables: The main component in a harness assembly is the wire or cable, which are used to transmit current and signals. Depending on the application requirements, the wire/cable may have different conductor materials, insulation materials, conductive materials and shielding materials.
Connectors: Connectors are the key components in a wiring harness assembly and are used to connect different electronic components, sensors, control units and other wiring harnesses. Connectors provide a reliable electrical connection and allow the harness assembly to be quickly and securely connected to other components.
Sheathing/Braided Sleeving: To protect wires and cables from external elements, harness assemblies are often covered with sheathing or braided sleeving. Sheathing/braided sleeving can provide protection, resistance to abrasion and chemical resistance.
Ties/Wire Ties: To keep harness assemblies neat and organized, ties or wire ties are often used to secure and bundle wires and cables in the harness. They help avoid tangling, interference and loosening of wires, improving the reliability and maintenance of the harness.
Identification Labels: For easy identification and maintenance, harness assemblies may come with identification labels to identify the different wires, connectors and features. This helps to quickly locate and distinguish the various components in the harness, improving maintenance and troubleshooting efficiency.
Electrical Wiring Harness (EWH) is a specific type of wiring harness assembly used in electronic equipment and electrical systems. It is widely used in modern automobiles, aerospace, home appliances, electronic communication equipment and other fields. An electrical wiring harness performs signal transmission, power supply and control functions by connecting various electronic components, sensors, circuit boards and other electrical parts together.
