Custom Wire Harnesses

Promark Electronics designs and builds custom wire harnesses that can withstand the most challenging environments and specifications. Our Value Engineering department is dedicated to finding the right product for each of your applications. Our sole focus is to develop a reliable, cost-effective custom wire harness tailored to your exact needs.

Custom Wiring Harness Services

  • We can incorporate custom colors in a wire harness, minimizing training time and speeding up installation and maintenance.
  • We can also embed a logo or text into overmolds on the harness, extending your brand or providing helpful direction for users.
  • We can provide custom branded cables printed with your name or logo.
  • We can provide customized cable coding and labeling.
  • We use dozens of specialized materials to combat environmental hazards or prevent corrosion.
  • We automate manufacturing whenever possible, including stripping, crimping, labeling and tie-wrapping, to decrease manufacturing time and increase quality control.


  • Each part of the manufacturing process is logged in our high-end ERP system, allowing us to create repeat builds that maintain exactly the same quality as the first.
  • Each step and every operator is monitored, and testing is performed at several stages within the manufacturing process. Every finished piece is also 100% tested according to our customers testing specifications and requirements.
  • Our facilities are ISO-9001:2015 certified for quality manufacturing practices.

Cost-Effective Value Engineering

  • We manufacture wire harnesses to suit your needs, in Canada or overseas. We can design in Canada and manufacture overseas for reduced development and manufacturing costs.
  • Your requirements determine the best way for us to work while our platform stays flexible to meet all of your needs.
  • We can design and build high volume runs, then store and ship the wire harnesses as needed, or create a small initial run and execute as many repeat builds as is required.
  • We are very flexible for our customers and can build high-mix/low-volume runs or high-volume/low-mix runs as our clients business needs evolve.
  • Since our high-end ERP system allows us to build identical wire harnesses in any facility, we can duplicate your production run in more than one plant, improving turn times and decreasing shipping costs.
  • Our team of engineers and designers will work from your drawings or help you develop aesthetically-pleasing wire harnesses that keep training and installation times to a minimum.
  • We work with our customers to create complete documentation, making future builds as dependable as the first.
