What are wire harnesses?

A wire harness is a group of wires, cables, and connectors that transmit electrical power or data. It is bound together and used to connect various components of a device or system and transmit signals between them. Wire harnesses are used in a wide range of applications, including telecommunications, information technology, construction, robotics and automations, appliances, and electronic equipment. See below for more details about applications for wire harnesses. 

Wire harnesses are typically made up of several components, including wires, cables, connectors, and protective materials such as conduit tape or shrinkable tubing. Conductive materials such as copper or aluminum together provide a means for attaching to other components. 

Given the diverse amount of applications, wire harnesses are typically designed and fabricated based on the specific requirements of the application. They are mostly custom-made or can be standardized for mass-production in a variety of applications. 

Where are they used?


When flying an aircraft tens of thousands of feet in the air, safety is paramount. This equipment includes extensive wiring especially for electrical and communication cables. In just one application, wire harnesses can enable power and all data transmission. 


There are about 280 million cars in the U.S. alone, organizing systems in vehicles is needed to help keep car users safe. Harnesses are absolutely necessary to save space. Lights, turn signals, and displays are just a few of the automotive systems using wire harnesses. They are also combined from various sensors that lead into fuse boxes and automotive control monitors or computers. 


Manufacturing environments use a number of machines that include extensive wiring, such as 3D printers and workstations. In these environments, stray wires can be a hazard. Wire harnesses can help keep facilities safe by ensuring reliable connections without the disarray. 


In a medical environment, efficient connections can be a matter of life or death. In such cases, something such as setting up critical care equipment must be established quickly and securely. Having the proper wire harnesses will help keep patients safe. In other, more permanent installations, harnesses can be used for imaging equipment. 

Wiring harnesses and cables are used in a variety of medical devices and equipment. In medical applications, wiring harnesses and cables are used to connect various components of the device, such as sensors, processors, displays, and power sources.

What are the benefits?

The benefits of wire harnesses are infinite. The two most important benefits are:

Decreased installation time: A good cable assembly can help group cables sensibly which speeds up installation working with complex systems.

Safety: Working with wiring can be dangerous but with the use of structural supports and insulation, the work can be made safer. Wire harnesses help with this and also keep stray wires contained.
