5 Points To Consider When Choose Custom Wire Harness Components

Do you want to convey an important message to your custom wire harness manufacturers? Perhaps, you want to give them the details of what is essential to the success of your custom wire harness? It is always a tough decision, especially because various points must to consider when choosing wire harness components.

The success of your design depends, to a large extent, on the manufacturer you rely on to produce results. Thus, it is essential to get in contact with an experienced manufacturer such as Cloom Tech to provide the right components for your wire harness.

Pay close attention to the details of this article.

1.The location of the Wire Harness (Answer Necessary Questions)

Various points are necessary for choosing custom wire harness. But, the first and foremost point is deciding on the location of the wire harness.

No knowledgeable organization carries out an important activity, such as choosing custom wire harness components without asking essential questions that are necessary for good results.

One of such questions includes “the location of the wire harness.” It is no doubt very important that you understand the location of your custom wire harness components. The choice you make in this regard determines the purpose of the wire harness.

Some of the questions you MUST answer are:

• Do I want this product to keep indoors or outdoors?

• Where will the wires and cables be housed?

• What are the temperatures that suit this product the most? Will the heat be hot, cold, or a fusion of both?

• How will the wiring systems be? Do I need to make use of a coil cord to stretch the product?

• How close can other substances such as chemicals or water be to this product? Any harm?

These questions are very necessary for developing the right type of product that applies to your needs perfectly. You and your organization need to provide adequate answers to the questions above before giving your product specification to a tech organization.

Every industry possesses the unique standards that set it apart from the rest. For this reason, some guidelines are required for custom wire harnesses as uniquely suitable for each industry, especially for wiring purposes.

With all these questions in place, you will agree that it is vital to work with a manufacturer or tech organization like Cloom Tech that understands the importance of location when choosing custom wire harness components.

2.Indoor or Outdoor Wire Harness: Any Difference?

Now, you may begin to wonder if there is any difference between the indoor and outdoor wire harness, right? Well, it is perfectly understandable if you start to doubt the need to spell out the differences between the indoor and outdoor wire harness.

Some factors need to be in consideration when choosing components for your custom wire harness. One of these is the type of wire to be used. That implies that there is a major difference in the kind of wire used for indoor and outdoor wire harnesses.

For the outdoor wire harness, the applicable type of wires to make use of includes a thick set of wires and even the use of a cable assembly. Cable assemblies are known to be durable, which makes them able to last for a long period.

Also, the wires can withstand wear and tear, and this makes it even more cost-effective for you. Another importance of the thick cables is that for outdoor purposes, the wires can cover long distances. Insulation materials for these wires are a thermoplastic rubber, vinyl, or shrink-wrapped thermoplastic.

The indoor use of wire harness requires that a wire harness used in place of a cable assembly. But, this is applicable when you are certain that the product will not expose to any unpleasant condition.
Another advantage of using wire harness for indoor purposes is the reality that it is cost-effective and allows electricity to transported over distances without incurring so much cost on resources. It is easier to do this because of the size and capacity of the wire harness.

But, one thing is common for either indoors or outdoors purposes; that is, how to house the product.

3.Materials of the Wire Harness That are Heat Rsistance

As a point for choosing custom wire harness components, you need to make decisions about the type of material to make use of.

Not all material for the wire harness can withstand heat. You must possess adequate knowledge about the stuff you want to use for your wire harness.

Various temperatures require different materials to enable it to perform at its optimum level. If you are not certain about the right type of material to use for your custom wire harness, you should discuss it with your manufacturer or the tech organization you hope to contact.

The material you choose for your custom wire harness component plays a vital role in ensuring that you experience the best from the use of the product. Therefore, this point must not undermine or regarded to be irrelevant.

As you kenw, the materials used for hot and cold weather conditions are different. For cold climatic conditions, it is important to make use of coatings that will is not prone to rigidity, such that the products will be able to adjust itself to the temperature and not produce unsuitable results.

Hot conditions are climatic conditions that require the use of materials that can withstand heat perfectly well. But, when the temperatures are extremely hot, then this requires that you pay more attention to the material.

So, to play safe, you should contact your manufacturer or the tech organization to help you in choosing the right material for your product.

You also need to bear in mind that some materials are suitable for extreme climatic conditions. These materials are wraps, jackets, and conductor insulations.

4.Various Types of Conductors

It would help if you certainly had the means to channel your current, and this is where the conductor becomes very important. Conductors play a vital role in the wire harness. It is the presence of the conductor that determines how signals are transmitted.

So, when choosing conductors as a component of your custom wire harness, you must ensure that you pay close attention to conductor types that can withstand corroding and overheating and still function perfectly well.

There are certain factors you need to consider when making decisions about the type of conductor you favor. They are:

Voltage/ bandwidth:

In your choice of a conductor, settle for one that can function well without becoming overheated or succumbing to pressures from heat.

Materials of the conductor:

Conductors use various materials. But, the most common material used for conductors is copper. Coppers are the most used because of its high conductivity.

Irrespective of the advantage of the copper material, it is noteworthy to mention that the copper is prone to corrosion. To make certain that you do not make the wrong choice, speak with your manufacturer to put you on the right track towards making the right choice.

5.Other Elements that Need Consideration

The other elements that need to consider are:


The terminals are one part of the custom wire harness that should not take for granted. The connection is indeed critical in creating a custom wire harness.

In choosing terminals, please pay attention to the location where you want it to be. Also, the use of the terminal should consider.

Strain relief:

The strain relief is necessary to extend the life of the custom wire harness. That implies that it is very important to pay attention to it, especially if you desire that your custom wire harness survives the test of time.

It designed to ensure that the current is constant and stays in place. By so doing, even when the current gets to the terminal, it is not affected in any way.


You would always need something that helps the wires stay in place. A disorganized wire would always leave your wires messy and make it difficult for you to get a hand of.

With the use of grommets, it is easier to get your wires arranged and orderly. Also, grommets make it easier for you to get in touch with any wire you need to make use of.

An advantage of choosing grommets for your custom wire harness components is that it aids installation and makes it easier for you to maintain your product easily.
