Whether you are designing a harness as part of a control system or looking to remanufacture an existing harness, our dedicated team has the expertise to assist you.

The design process begins with a consultation, either in person or via email, working with you to ensure your harness wiring specifications are met.


Your harness is then drawn to the agreed upon specifications using our specialised harness design software. Our specialised program lists the types of connectors to be used, conductor sizes, lengths of each branch, pinout for all the connectors, and the protective layering.

Once a design is finished, we assign your/the harness a unique part number to streamline future ordering. This guarantees that your harness orders are built the same every time, unless changes are required or requested, which we are happy to assist you with.


Our harness design software allows us to generate a wire cut list before manufacturing commences. Each conductor for the harness is printed and cut to length using our specialised ink-jet printer. The wire printing, is an important addition to the manufacturing process, in which we label wire identification on to the wires. This process means that the wiring diagram can be referred back to as required and can aid in fault finding.

We utilise a variety of tinned copper cabling for all our harness manufacturing, depending on your specifications we have either XLPE (TXL) or “Mil-Spec” PTFE sheathing. These variants of tinned copper cable offer better resistance to corrosion, higher temperature ratings, greater current handling capability, and oil/chemical resistance over standard PVC sheathed automotive copper cabling.

Terminating the main connector and building from that point allows for a neat uniform harness. Whilst also reducing the chance of wire fatigue in the harness. The main layout of the harness is formed using standard harness taping, or in some applications, variations of heat-shrinks or silicone glass sleeving. In the final steps of manufacturing each connector is terminated correctly and labelled as per the design schematics. The harness part number tag is then installed before the harness undergoes our quality control and testing process.


All of our harnesses go through our quality control and testing processes. Initial testing is completed by the Manufacturing Technician, who checks connectors, lengths, and correct pin outs. Once the initial testing is completed, our Quality Control Technician then undertakes a thorough inspection of the harness, before the harness can be marked and signed off as ready for the harness braiding process.


Braiding is the final stage of harness production. We have two options available to suit your needs. We have a PVC coated nylon braid that is suited to most applications, or a PVDF coated nylon braid for harsher environments.

Harness braiding offers superior quality compared to nylon conduit, providing higher resistance to temperatures, oils, and abrasive conditions. Where a nylon conduit harness fills with moisture and debris, causing premature conductor corrosion, a braided harness allows moisture to escape providing you with a superior harness solution.

We have a number of coloured yarns and traces available to choose from for your harness. Harness braiding provides a clean and professional finish for your harness.
