Custom Wire Harness-The Complete Guide

A wire harness is imperative to equipment as it carries power and signal through it. A custom wire harness helps in connecting various components of a device. Otherwise, they will become useless.

A collection of several wires packed in a bundle is a wire harness. These wires are put together with a band, sleeve, tape or lacing as it stops them from branching out. The wire harnesses carry electrical and power signal through them.

They help components of an equipment function properly. It’s the basis of functionality for all the equipment involved in aircraft, computers, audio systems, and so on. If a wire harness doesn’t connect the power source to the component of equipment, it will fail to work.

In this article, we will inform you about the key factors that you must keep in mind while buying a custom wire harness. It’ll help you pick out the right supplier/ distributor/ manufacturer to mass produce your custom wire harnesses. 

Custom Wire Harness

Step 1: Consider the cost-effectiveness of your custom wire harness

You might have an urgent project that requires urgent custom harnesses. The first thing you need to consider when placing the order of a wire harness is the cost and the quality of the product. You can either get low-quality products that are cheap or invest in high-quality, competitive products.

Low-quality products are not durable because they require constant maintenance and repair. Therefore, they’d prove to be expensive in the long run. You might also get a wire harness that uses expensive material but doesn’t suit your requirements at all. You must keep your requirements in mind while making a choice.

Here’s how you can understand the costs and make the right choice with your custom wire harness.

Time Costs:

The quality of the product can determine how much your company will end up spending on the custom wire harness. A poor-quality wire harness can affect the operation of your equipment. Not only will they make the machinery inefficient but will also affect the implementation of it. Cheap and inferior quality products cause unnecessary trouble as they require a lot of maintenance. Hence, they end up costing more than the actual price of the wire harness.

Money Costs:

Even the smallest of the harnesses are important to any project. A wire harness, despite its size, helps in the functioning of any equipment. Inexpensive products are generally low in quality. If your wire harness is too cheap to believe, the chances are that it isn’t well made. For example, the terminal and the line number of the wire harness might not match.

It’s also possible that the tensile test of the harness is not closed. Even if they work properly,  low-quality harnesses aren’t durable as the product doesn’t meet the industry standards. So, you may end up repurchasing the cable and spending double the amount of money you already have. Therefore, low quality and cheap products always end up being more expensive than a good quality product.

Finding a reliable manufacturer or supplier of custom wire harnesses is of utmost importance. They understand that efficient companies don’t delve into time-consuming and laborious things. This way, you always get your product well tested and in due time.

 

Step 2: Consider the hard power of the Wire Harness Supplier.

1. Look at the supplier’s equipment

Industries like automobiles, aerospace, military, electronics and more make use of the wire harnesses. Wire harnesses take less time to install since you don’t have to deal with single wires. The absence of any loose wires also reduces any chances of malfunctions and short circuits. Wire harnesses can withstand heat, abrasion, and chemicals and are thus, quite durable. They can also improve the performance of the equipment.

 

Your custom wire harness is only as good as the supplier who makes them. You should, therefore, always have a look at the kind of machinery and equipment they have. If their equipment is not up to date, they won’t be able to produce wire harnesses that meet the highest of industry standards. Old technology also means the inability to produce a more diverse range of products. So, if your requirement is unique and demands a different kind of wire harness, you should pick a supplier who’d be able to design them all.

2. Qualification confirmation for wire harness suppliers 

The wire harnesses that you use in your company must meet the quality standards of the industry. It means that the suppliers that you choose to provide high-quality harnesses themselves. Every supplier must have the ISO 9001 certification for their organization. An ISO 9001 certification means that the company constantly provides products that meet the customer and regulatory requirements. So, if your supplier has an ISO 9001 certification, they’d produce high-quality wire harnesses that’d meet your project’s requirements.

 

Step 3: Talk to the wire harness supplier.

 When designing a custom wire harness, you should always talk to the supplier first. Discuss your requirements and design with the suppliers and learn if they’d be able to provide you what you want. You should always notify the supplier of the environment in which you are using the harness. This way, they’d be able to decide the appropriate material for it. The amount of pressure that the harness would be in also decides the kind of components it’d have.

Here’s how you can discuss with your supplier and choose the right components for your wire harness.

1. Conductors

Copper is the best metal conductor around. But some wire harnesses might require a different material for a conductor as copper corrodes easily. The conductor should be able to carry signals properly and it’s carrying capacity shouldn’t exceed the voltage.

2. Terminals

A terminal is put at the end of the wire and connected to the assembly. The role of a wire harness is dependent on the location of its terminal and how it’ll be used.

3. Connector

Connectors join different wires together. Some connectors are permanently fixed into the system while the others are removable and portable.

4. Strain Relief

Wire harnesses need to be flexible as they connect various components of the equipment. However, the place where the harness meets the component must be rigid. A strain relief provides the harness that rigidity so that it can withstand the pressure at the connection point.

5. Grommets

Grommets keep the wires secure and in their right place. They keep the system organized and make installation and maintenance an easier job.

6. Insulation Jacket

An insulation jacket protects the wire from exterior conditions like water, heat, chemical leaks and more. The appropriate materials for insulation are PVC, rubber, and polyurethane thermoplastic.

You can mention these components while discussing the product with the supplier and see if they’re professional enough.

 

Step 4: Verify the supplier –Start with a small order.

Even after you’ve learned enough about the supplier and the quality of their work, don’t jump in with big orders. Start with a small sample list and less complex wire harnesses to test the quality of the product yourself. You’ll also get familiar with the speed at which the supplier produces the wire harnesses. You can repeat this process with other suppliers. When you confirm the quality and speed of the product, you can see which one produces the best product in the shortest time, you can order in bulk.

Another important factor in choosing the right supplier is their after-sales service, which a lot of people tend to ignore. We’ll now learn why it’s an important factor.

 

Step 5: Excellent after-sales service

Even though you’re happy with the product that you’ve received, you can’t rule out any issues that might happen. There is always room for error caused by small omissions or problems that happen due to the rigorous use of the product. The only people who’d be to handle the issues well are the supplier of the product.

It’s imperative that the suppliers take responsibility for their product. They must provide the required services even after the sale has happened.
