  1. What is a Wire Harness?

  2. A wire harness, often referred to as a cable harness or wiring assembly, is a systematic and integrated arrangement of cables within an insulated material. The purpose of the assembly is to transmit signal or electrical power. Cables are bound together with straps, cable ties, cable lacing, sleeves, electrical tape, conduit, or a combination thereof

  3. WireHarnesses vs. CableAssemblies • Wire harnesses are often confused with cable assemblies however, the two are quite different. The main difference is that a cable assembly normally has only two ends, whereas a wire harness contains multiple breakouts (ends) that run in many different directions with multiple terminations on each breakout. • Wire assemblies are most commonly used in the transportation industry, including automobiles, buses, trucks, and planes. Construction machinery, industrial equipment, electronics and white goods (household appliances) will also be constructed using wire harnesses.

  4. Wire Harness Assembly Benefits • Decreased installation time: Many vehicles require miles of wiring in order to operate. A wire harness assembly process greatly simplifies the manufacturing of these vehicles by integrating all the wires and cables needed into a single apparatus. The installation then becomes a simple matter of “dropping in” the harness, rather than running all of the wires individually. • Security and safety: When wires and cables are bound within a single harness, the individual components are more secure against the adverse effects of vibrations, abrasions and moisture. Space is optimized and the risk of an electrical short is reduced because the wires have been constructed into a non-flexing bundle. The risk of electrical fire is also reduced when the wires are bound within a flame-retardant sleeve.

  5. Why Are Wire Harnesses Assembled Manually? The manual processes include: • Installing terminated wires in various lengths • Routing wires and cables through sleeves and conduits • Taping breakouts • Conducting multiple crimps • Binding the components with tape, clamps or cable ties

  6. Post Production Wire Testing • The final step of the assembly process is to test the harness for electrical functionality. This testing is done with the aid of a pre-programmed test board. The test board is programmed with the required electrical characteristics and the completed harness is then plugged into the board and checked for faults. • Hopefully, this blog has answered most of your questions regarding wire harness assemblies. If you are wondering if custom wire harness might be right for you.
