FSW contains other products and information you need, so please check it out.

Custom Wire Harnesses

Wires and cables are indispensable tools for a wide range of today&#;s home and industrial systems, and harnesses allow technicians to create orderly, carefully fitted wiring solutions for any type of environment. Depending on the specific needs of an application, these harnesses can be built to accommodate systems up to 600 volts (UL) or volts (military), with high performance at temperatures ranging from -65 °C (-85 °F) to 250 °C (482 °F).

When evaluating a new cable or wire harness solution, remember to carefully consider the specific environment it will be used in and the temperature and conditions it will be exposed to. Evaluate all of the different cable types you may be able to use; custom wire and cable harnesses can be crafted with nearly limitless style and material options, including:

  • Wire ties
  • Lacing
  • Insulation materials of all kinds
  • Custom colors
  • Heat-shrink coatings
  • Custom labeling or barcoding
  • Four-color ink stamping
  • Individual tagging
  • Independent circuit IDs
  • Polypropylene, nylon, and paper fillers
  • Custom shielding

We take a strategic engineering approach to select the most ideal shielding and connectors for your application. At the same time, we take into account all applicable regulatory standards to ensure that your final harness is safe, reliable, compliant, and effective.

Other factors that bear on harness design include:

  • Whether the harness will be exposed to continuous flexion

  • If the harness will be used indoors or outdoors, and under what specific conditions

  • How many circuits and conductors are required for the assembly, as well as their characteristics

  • Level of voltage to be carried

  • Potential exposures, including chemicals, corrosive fluids, weather conditions, and moisture from other sources

  • Maximum, minimum, and average operating temperatures, as well as potential fluctuations

  • Local safety and environmental regulations that might impact component selection, installation, and inspection

  • Routing, breakouts, general shape of form

 

Wire Harness Applications

Since wire harnesses can be used to solve such a diverse range of interconnection challenges, they are used extensively throughout myriad industries. Virtually any industry that relies on cable arrangements can benefit from the use of wire harnesses. The following sectors, among others, often rely on wire harnesses to maximize efficiency and protect employees against the dangers of haphazard wiring:

  • Aerospace.

    Wire assemblies are used in an expansive range of aerospace products, such as drones, satellites, and aircraft to facilitate the transmission of power, communication, and more.

  • Automotive.

    Wire harnesses are critical for saving valuable space within automobiles within the dashboard, under the hood, lighting/signals, and more. They are also important for organizing complex wiring in such a way that technicians can easily identify their purpose.

  • Medical

    . Hospitals and clinics rely on wire harnesses to organize and protect wires in and between equipment, including crash carts, diagnostic and imaging equipment, dental equipment and more.

  • Telecommunications

    . Wire harnesses optimize use of space in a variety of telecommunications equipment, such as modems, routers, repeaters, and a variety of other communication and broadband equipment.

  • Information technology

    . Nearly all computers, laptops, servers, and other IT technology contain wire harnesses to optimize space and organize wires for easy identification and installation by technicians.

Benefits of Wire Harnesses

Wire harnesses would not be so widely used if they didn&#;t present substantial benefits for wiring applications. Among other advantages, wiring harnesses benefit companies in the following ways:

  • Decreases cost compared to multiple individual assemblies

  • Improves organization, especially when a system relies on hundreds of feet of complicated wiring

  • Decreases installation time for projects involving extensive networks of wiring or cabling

  • Protects conductors from the elements outdoors or from chemical and moisture exposure indoors

  • Provides a safer work environment by cleaning up loose or scattered wires, maximizing space, and preventing trips and damage to wires and cable

  • Enhances safety by minimizing the risk of shorts or electrical fires

  • Decreases installation and maintenance time by potentially minimizing the number of connections and organizing components in a logical configuration

The many benefits of wire harnesses stem from very simple design principles. Sheathes protect wires against abrasion or exposure to hazards, minimizing the risk of workplace incidents. Connectors, clips, lacing, and other organizational strategies drastically reduce the amount of space that wiring must occupy and ensure that technicians can easily locate the components that they need. For equipment or vehicles that regularly contend with a web of lengthy wires, a wire harness is sure to benefit everyone.

High-Performance Materials

In addition to ensuring optimal organization, a high-quality wire and cable harness will provide reliable insulation and protection for the conductors within. There are many options for durable harness materials, and it&#;s important to select what is most beneficial for your needs.

Some of the most common insulator materials include:

  • PVC, or polyvinyl chloride
  • SR-PVC, or semi-rigid polyvinyl chloride
  • Cellular polyethylene
  • EPDM, or ethylene propylene diene monomer
  • TPE/TPR, thermoplastic elastomers
  • PE, or polyethylene
  • Both low- and high-density polyethylene (LPDE and HDPE)
  • Cellular, or foam, polyethylene
  • PU, or polyurethane, as well as polyurethane and nylon blends
  • Low-smoke plenum copolymers
  • Polypropylene (PP) and cellular (foam) polypropylene
  • FEP, or fluorinated ethylene propylene
  • TFE, or tetrafluoroethylene
  • PTFE, or polytetrafluoroethylene
  • ETFE Tefzel
  • PVDF Kynar
  • ECTFE Halar
  • IRR/PVC, or irradiated polyvinyl chloride
  • XLPE, or cross-linked polyethylene
  • Vinyl

In choosing between these and other options, it&#;s important to take into account environmental variables such as operating temperature and moisture. The presence of moisture, for instance, can necessitate a water-resistant material like polyethylene to avoid damage to the conductors.

Choosing The Right Wiring Harness Type -

What&#;s The Right Wiring Harness For Your Car?

Wiring a car can be a daunting task even for a professional. Not all wiring is created equal including how they are laid out. Sort of like how some people prefer to buy a complete suspension kit and others prefer to piece things together. We all work differently and wiring is the same way. We see there are several different versions of wiring out on the market and wanted to know the different styles available to help you choose the best one for your car. We contacted Andrew Erichsen of Painless Performance to help explain the different harnesses options.

We break down each one below, but Andrew also had a video to share with us that goes over each wiring harness style as well.

Direct Fit

&#;The first and foremost is a Direct-Fit harness. These are harnesses that have all the wires pre-terminated so you just have to lay it in the car and pop the connectors into place,&#; explained Andrew. Generally these are OEM replacements but some of them like the ones Painless Performance offers have upgrades. These upgrades would include mini-blade fuse box and additional circuitry for updated wiring requirements. Out of any wiring harness, these would most likely be the easiest ones to install, especially if you can take out the original harness to see where the new one goes.

The downside to these is that if you want to change how the wires are laid out or change the ends to something different other than stock, you&#;ll have to cut and modify the harness anyways. The other consideration is that these will use the direct fit factory bulkhead connector. If you wanted to tuck those wires away elsewhere, you won&#;t have that option.

Universal

The other end of the spectrum is a universal wiring harness. &#;These are customizable wiring harnesses that can be adapted to fit into just about any car. These give you the most adaptability to wire everything yourself,&#; continued Andrew. Now this might be a bit intimidating but Painless includes a 1/2&#; thick full color instruction book. These books explain what every single wire does, how it needs to be hooked up, and gives you different configurations for different applications. All the wires are labeled with a short description and number &#; that number you can look up in the instructions.

These are going to offer maximum flexibility to fit any chassis but you&#;ll need a bit of knowledge and planning to figure out every terminal to get it hooked up properly. These can be ordered with either a grommet or bulkhead so you can fish the wires through anywhere you need.

Pro-Series

Between a Direct-Fit and a Universal harness is Painless&#; Pro-Series harness. We actually installed one of these a few years ago in our Project Way-Gone. These harnesses are upgraded from factory with extra circuits, but don&#;t come pre-terminated like a Direct-Fit harness does but does come with every terminal or connector you&#;d need. All the wires are terminated at the upgraded fuse box though. The reason you&#;d want this is so you can lay the wires and tuck them away exactly how you want, not how the factory did it. The wires are extra long which allows you to do a much better job of hiding the wires than the factory. Same as all their harnesses they are color coded and printed with a number inside the instruction manual.

The Pro-Series can also be had with a bulk-head style under hood harness like a Direct-Fit, or a grommet style like the Universal. When we installed our Pro-Series harness we opted for the grommet style so we were able to move the wires over and out of the way a bit and it just looked cleaner to us than this big bulkhead on the firewall. They also offer these in a trunk mount version too where the fuse panel is mounted in the trunk instead of under the dash.

Fuse Box

There&#;s another style of wiring on the market where it&#;s the opposite of what Painless offers. In these kits the wires are terminated at the ends for whatever they are connecting to, but unterminated at the fuse panel. This is sort of like a Painless Pro-Series but instead of terminating the ends, you have to terminate them at the fuse box. The downside here is that the fuse box has to be a little bit bigger to accommodate those connections. Again it&#;s more of a user preference than anything.

As you can see just like how there are many different versions of brakes for your ride, there&#;s many different versions of wiring harnesses as well. There&#;s no right or wrong answer, simply a matter of what works best for your application and needs along with your preference.
