Commitment to quality

In our 30-years of experience, we have developed a firm commitment to delivering the highest level of quality possible to our clients.

We bring much more to the table than just competing on cost. If we see ways you could achieve cost savings or other efficiencies in your project, we can provide suggestions for improvements and alternative design options.

Using our comprehensive knowledge of designing high quality wiring harnesses, we will carefully consider what elements your harness will be exposed to so we can ensure it is designed and built to last. Details we will account for in the design can include:

  • Does the harness need to be protected with wrapping, weaving or sheathing?
  • Is UV treatment required for exposure to the sun?
  • Is moisture protection required for exposure in refrigerated environments?
  • Will there be exposure to vibration and heat from an engine?
  • How will the harness be routed and will there be any access challenges?

Our process

We understand the importance of clear communication when it comes to ensuring a project is completed in full and on time. This is why we will always work closely with you from initial consultation to delivery of your new harness.

We believe it’s important for us to get an understanding of your project objectives and challenges prior to putting together a proposal. Our team will discuss your needs at length as well as your timeframe and delivery requirements.

We’ll also give you an approximate indication of lead times and can also provide some advice on how to potentially improve on your design specs.

Depending on the scale of your project, we will determine whether a wiring harness prototype or sample will be required for preliminary testing purposes. Once the prototype has been tested, we will take on board your feedback and make improvements if required to ensure you are completely happy with the design of the harness.

Once we have a thorough understanding of your needs, we will put together a proposal for you. For complex projects, the proposal will include a detailed “scope of works”.

When we’ve received your approval to proceed, we will lock your wiring harness project into our workflow and provide you with accurate scheduling for completion.

Throughout the design and assembly processes, you will have a single point of contact with one of our expert team members.

Testing and delivery

Our stringent testing measures allow you to be confident you won’t have any issues and there will be no delays to your project.  

We test every single cable that we assemble before leaving our premises. In cases of complex wiring harnesses, they are often tested multiple times.

Once your order has been completed, we will ensure its delivered to you as per the agreed upon timeframe, ready for you to install.
