What’s a Harness?

A harness is a series of cables or wires used to transfer electronic information or signals. It is commonly used in vehicles, heavy equipment, and power processing plants. The manufacturing process is still done manually, but it is relatively short.

Also known as a harness or cable assembly, a harness is a series of cables or wires aligned to provide efficient transfer of electronic information or signals. The number of wires included in the cabling will depend on the intended purpose of the cabling and the amount of current or data that must be transmitted to complete the essential tasks. Typically, some method of securing the cables in place is used, a measure that helps prevent problems that could interfere with the normal operation of the individual cables.

A harness can be used in any number of different devices that rely on the use of electrical current for operation. For example, it is not unusual to find this type of wiring used in many types of vehicle engines. Bundling the cables allows power to be transferred to different engine components which in turn helps support the overall operation of the engine with a high level of efficiency. In this application, the wiring included in the harness will often be protected with some sort of sheathing and secured in place with clamps to minimize the chance of damage to the wires during normal operation.

The heavy equipment used in many factories, as well as the wires and cables commonly found in power processing plants, will also use different wiring configurations. The size of the cabling will depend on the number of cables included in the setup, which in turn is often determined by the amount of energy that needs to be conducted through the system itself. As with most types of electrical equipment, a harness or assembly must meet safety standards set by regulatory agencies and is routinely inspected for any signs of wear that indicate it is time for replacement.

While computer technology and other modern tools are often used in the design stages of creating a wire harness, the actual manufacturing of the wire harness is normally still done manually. This involves carefully assembling all involved components and properly aligning any wires or cables included in the project. Despite the manual manufacturing process, the time required to assemble a single harness is relatively short, allowing manufacturers to produce enough product in a typical workday to make the effort profitable.
