Cable assemblies

"without quality cable assemblies your race is over before it’s even started; use our expertise to win races"

From our years of experience in military harnessing we can offer the service of harnessing for the motorsport industry. We design and manufacture motorsport cable assemblies, operating in the harshest of environments utilising Raychem system 25 materials, autosport and military interconnection systems using Daniels tooling.

Automated machinery really reduces labour times


We can build any type of custom motorsport cable assemblies for any type of motorsport wiring application, from full chassis and engine looms to sensors and pit equipment. We work with wires as small as 32AWG to 4/0AWG. Where we excel best is at the design stage, our in house engineering department can design the cable assemblies around what the customer requires, instead of the customer having to make use of what has already been designed. We have great experience of this from our military background. We can specify connection systems that are superior but not necessarily at a superior cost to the customer. We also have our own CAD design team in house and at the same time can work easily from other drawing packages such as VISIO.
Over 30 years of business we have invested in some very sophisticated tooling, including fully automated tooling. This is what separates us from our competitors. In quite few instances we can actually engineer the production of a loom so that it is cut, crimped and inspected all by robotic CNC machinery. This tooling investment is way over £500,000 but was only sustainable due to the other market sectors St Cross are involved in.
Our operators are trained to Raychem system 25 wiring techniques as well as some defence standards. We have a very strong team in purchasing who negotiate hard for the best prices and delivery, we work direct with connector and wire manufacturers; we try hard not to use distributors. All our hand crimping tooling is calibrated and each one has its own calibration record so the customer has confidence our manufacturing carried out has no drop off in quality. We also have in house tensile testers, and these results are kept on file for 5 years. All cables from Motorsport Cables are 100% electrically tested using Cirris equipment including CH2 testing technology. This enables us to carry out HI POT 4 point testing; again this is recorded and kept on file for 5 years. We can produce one-offs motorsport cable assemblies to full batch quantities, and our flexibility allows us to react quickly in some cases. We have a dedicated team for R&D projects. Our excellent quality record means that you know that the cable assemblies will work first time when needed.
