When you’re on the search for a cable harness manufacturer, it’s easy to feel overwhelmed. Despite many options appearing similar at first glance, they vary in terms of industry experience and capabilities required to produce efficient cable harnesses. The good news is there are certain qualities that can guide you in making an informed decision.

Qualities of a Cable Harness Manufacturer

1. Tailored quality checks

Every maker has their basic checklist for making sure things are right. But the best ones? They go the extra mile. You want to team up with a vendor that gets what your product needs and makes their checks fit those needs perfectly. This is super important in areas like health or defense, where the small details can’t be overlooked.

2. Integrated solutions

Getting someone to build your cable and wire harnesses is great, but finding a manufacturer that offers more can really take the weight off your shoulders and add extra value. How about choosing a company that also does engineering? When it’s time to introduce a new product, it’s awesome to have a manufacturer that can check your designs to make sure they’re as good as they can be for making things easier and better.

Taking it up a notch, think about where those cables and wires will end up. If they’re part of a bigger piece, like a component or the final product, you could make things simpler by choosing a manufacturer that can handle the whole shebang. A setup where one company does it all—from cables to final assembly—can save you money and cut down on the hassle of dealing with multiple suppliers.

3. Comprehensive Certification Compliance

Leading cable harness manufacturers hold a wide range of industry certifications. These certifications serve as proof of their commitment to meeting rigorous quality, safety, and regulatory standards. Here’s a rundown of some key certifications to watch for:

  • ISO 9001: This is a universal standard for quality management systems across numerous industries. It shows a commitment to consistent quality and customer satisfaction.
  • TL9000-H 6.0/5.0: Shows a company meets the quality requirements specific to the telecom industry.
  • UL (Underwriters Laboratories): A nonprofit certification agency recognized by OSHA, indicating products meet safety and quality standards.
  • C(UL): Signifies compliance with Canadian safety standards, which may differ from those in the U.S.
  • ETL (Electrical Testing Labs): Indicates products meet comprehensive quality, health, environmental, safety, and social accountability standards, as recognized by OSHA.
  • ISO 13485: Specific to medical cable assembly, it confirms a company meets high-quality requirements in medical device manufacturing.
  • NADCAP: An aerospace industry accreditation that identifies manufacturers producing high-quality products through superior processes.
  • AS9100 REV D: Essential for aerospace products, this certification indicates adherence to quality standards in the aerospace sector.

4. Technical expertise

Designing a cable harness is a complex task that requires a manufacturer with special skills and knowledge. When designing a harness, factors like electrical needs, space limits, and where the harness will be used all come into play. Working with a manufacturer who has deep expertise in these areas offers benefits like:

  • Better design: They can help tweak your harness design to make sure it works great and lasts long. Their advice helps cut down on problems and makes sure the harness fits your needs.
  • Faster production: Skilled manufacturers pick the best materials and methods to speed up making your harness. This means your harness is ready quicker and costs less, but still works great.
  • Solving problems: Manufacturers with lots of know-how can come up with clever solutions to fix issues. They’re good at thinking outside the box and making sure your project turns out just right.

5. Scalable production

Ensure the harness manufacturer you’re looking at can quickly set up dual production capacity in a different location if needed. This helps avoid problems when there are complications (from things like pandemics, labor strikes, port shutdowns, etc.). Some companies can take up to a year to do this because it’s complicated and needs a lot of work. But others can get it done in just weeks. So, pick a vendor who can best protect your interests in case of unexpected situations.

6. Efficient sourcing

A cable harness assembly comprises various types of cables, each with its own array of cable types—power cables, fiber optic cables, and copper cables for data. Additionally, different harness assemblies require ferrules, connectors, terminal blocks, bushings, and other components.

This makes it essential to choose cable assembly services capable of swiftly and efficiently sourcing every necessary component for your harness. A company with excellent sourcing capabilities can not only obtain the exact components you need but also save you money in the process.

7. Proactive communication

Precision and reliability stand as non-negotiables in the cable harness industry. Proactive communication acts as an enabler in this regard—it diminishes risks, streamlines processes, and guarantees the punctual delivery of superior products. Therefore, it’s crucial to opt for a manufacturer with proactive communication skills.


These are the essential qualities to consider when evaluating cable assembly manufacturing options. Remember to prioritize manufacturers who demonstrate a strong commitment to quality, technical expertise, comprehensive certification compliance, and the ability to meet your specific needs. Such manufacturers can support the success and longevity of your projects and products in any industry.
