Are you ready to take your connectivity game to the next level? If you’re at the point where you’re ready to order a custom cable assembly, wiring harness, control panel, or any other connectivity solution you will need to have some crucial information ready to provide to the manufacturer you choose to partner with. Don’t miss out on the opportunity to get the best solution for your needs. Get prepared and get connected today!

Top 10:

  • A drawing—preferably an engineer’s drawing or schematic, but crayon works too.
  • Lead Time
  • Quantity
  • Connectors
  • Cable
  • Length
  • Are substitutions allowed?
  • What certifications do you need?
  • Do you need a prototype?
  • Do you have any special requirements?


You will need to have a drawing of the cable assembly or wiring harness for your manufacturer to review. The manufacturer will need this to determine what production resources will be required, but also so they can start sourcing the components. It’s possible to reverse-engineer an existing cable assembly or wiring harness without a drawing (We do it all the time!), so bring this up early so your manufacturer can start the process right away.  A drawing will typically include a detailed bill of materials, assembly instructions and a wiring diagram.  Take a look at the link below for an example of a wiring harness drawing.

Lead Time

You will need to provide a desired delivery date.  Let your wire harness and custom cable assembly manufacturing partner know if you have any flexibility with your lead time requirements.  For example, accepting partial batch deliveries is a good way to keep your production line going, while providing your manufacturing partner with a little more time to complete the order.  Depending on your industry and requirements, it could be possible to provide substitutions with the same form, fit, and function.  Consequently, you should let your manufacturer know so they can provide you with options (that could possibly save you time and money!).

Special Requirements

Additionally, if you have any special requirements such as Canadian Content Valuation for ITB/IRB offsetting, Controlled Goods Program certification, or US/Canada Joint Certification Program,


you should make sure to let your manufacturer know in advance.

So there you have it, you are ready to make the call! If you are in need of custom cable assemblies or other connectivity solutions give us a shout!
