What You Need to Know: Assembling a Custom Wiring Harness

A wire harness can be found in almost every electronic device or machine. It started becoming a more popular way to organize and reinforce the wiring system in appliances and automobiles in the early 1920s. Today, wiring harnesses are more sophisticated and have adopted more durable types of materials for different applications. Each type of wire harness is made different and unique according to the device it was intended for.

A wire harness is normally made up of hundreds or even thousands of parts. Each part serves different functions to efficiently distribute electrical signals throughout the machine or device. It also acts as the main exterior covering that protects the different components in an electrical system. Though the main purpose of a wire harness is straightforward, it is considered an essential part of any device or machine that utilizes an electrical supply.

Making Your A Custom Harness

Custom wire harnesses are very common especially in the electronics industry and the automotive sector. Knowing how to put together an efficient wire harness can come in handy when it comes to weekend electrical projects. For many car enthusiasts, having the proper knowledge about wire harnesses can be useful when it comes to making vehicle modifications and upgrades.

Before starting a project that requires a wire harness assembly, it’s important to consider all the factors that are necessary for the production process. Making a wire harness not only requires specialized knowledge but also specific tools. Here are some of the instruments that are commonly used when assembling a custom wire harness.

Breadboards– When figuring out the layout of your wiring system, breadboards are the perfect tools to set up temporary connections. The holes within a breadboard provide a temporary pathway for wires and other components without soldering. It also gives you a vision of how practical the wiring layout is.

Digital Multimeter- Testing whether the wirings in your circuit are working properly is an important part before establishing permanent connections. A digital multimeter allows you to determine if the interconnections in your wiring layout can transmit electrical signals properly. It can test both the resistance and voltage in a temporarily mounted custom wire harness.

Soldering Iron- Using a soldering iron allows you to establish permanent connections and reinforces the connections in your wire harness. A soldering iron is mostly used during the final assembly so you might not need one while testing connections on a breadboard.

Schematic Diagram Knowledge

Of course, before getting started with the assembly process, it’s important to make a schematic diagram of your wire harness layout. A schematic diagram should also be clear and accurate especially if you plan to have your design assembled by a manufacturer. Most people in the field of electronics use CAD software when making a harness design.

CAD offers a wide range of tools that you can use when digitally drafting your schematic diagram. Familiarizing yourself with CAD software also allows you to better understand other wire harness layouts when repairs need to be done to other electronic devices.
