Wiring Harnesses

For over 40 years Renvale has provided World leading wiring harness design and manufacturing services to the automotive & motorsport industries.

Renvale is the longest standing designer and manufacturer of bespoke wiring harness solutions to the Motorsport industry. Our founder, Tony James, pioneered the use of military-style connectors on the Lotus-Cosworth T91. Since 1982 Renvale Ltd (previously known as Tony James Component Wiring) has built up an enviable client portfolio spread across F1, Formula-E, MotoGP, Superbikes, WRC, WTCR, WEC, IndyCar, and various GT formulae. As well as the above, Renvale has worked on specialist OEM projects including diversification into other sectors such as marine, automotive and R&D Test facilities.

Our key strength is managing, designing and supplying a completely bespoke, robust, integrated turnkey solution to suit budgetary constraints. Through experience, expertise, relationships and continual improvement, our ethos and focus is always balancing Quality, Cost, Delivery and Service. We have the latest Cirris CH2 electrical test capabilities, with a dedicated Test & Inspection area to oversee build quality and verify circuitry. We also incorporate a robust quality management system with full ISO 9001:2015 certification, have the ISO 14001:2015 Environmental Standard and Cyber Essentials Plus certification, so you can rest assured your business is in safe hands.

A quick turn capability to speed development program and collaboration with a European partner for technical expertise and additional overflow capacity is also on hand. With 40 + production techs, x3 T&I, x5 Engineering, x4 Production Mgmt Team supported by QA Engineer, Procurements, Admin and a dedicated hands-on Mgmt Team.

Manufacturing Capability

We have over 63,000 + hours of wiring harness production capacity pa. We pride ourselves on our in-house training capability, which is monitored via personal development records and skills training matrix.

Growth is vital to our team, we continually develop their skills and our customer base. Our Staff intake July/August 2018 were fully conversant with Renvale manufacturing processes and productive on complex, medium-sized assemblies (50-100 hour harness builds) within a 6 month time period. Our latest intake from July 2019 looks to replicate and exceed this learning curve.

  • High voltage automotive wiring for battery and hybrid vehicles.
  • Builds ranging from basic test leads through to full vehicle harnesses.
  • Power distribution units, ECU systems, control panels, lighting and battery wiring harnesses.
  • Engine harnesses for high temperature and hostile environments.
  • On-site design & prototyping service for special projects.
  • All wiring harness technicians are certified IPC-A-610 application specialists.

Design & Prototyping

Renvale’s design engineers have over 100 years of combined experience, we can guarantee a seamless journey through every aspect of the design process.

Design engineers are on hand to help through every stage of the design process, creating a streamlined strategy to quickly bring your project to life. We can take your drawings and modify them into the desired format, or draw from the ground up. We commit to taking all the hard work out of our client’s hands and create a seamless journey to production.

Our integrated design toolset incorporates the latest software from AutoCAD, SolidWorks and Visio. This along with our years of experience enables us to easily develop traditional wiring harnesses, all the way through to incredibly complex enclosures and the latest high voltage systems for battery powered vehicles.

All drawings are fully checked and guaranteed to be error free. 3D dynamic wiring harness simulation finally enables us to check each harness fits perfectly into the vehicle structure. We then generate the bill of materials and wire cut lists, maintaining maximum efficiency through the entire process, leading to optimized harness development and a reduction in lead times.

Unrivalled Quality

Our dedicated quality control team have all undergone an unrivalled training programme which forms the benchmark within the industry.

Every Renvale wiring harness undergoes an industry leading, rigorous 40-point quality control check procedure by our dedicated test and inspection technicians.

Firstly, during the initial design stage, the need for line inspections are initially identified and finalised during prototyping, identifying any potential points, such as splices and transitions.

The wiring harness then undergoes a full visual and dimensional check before moving onto Hi-Pot testing with the latest Cirris harness test equipment. Our department utilizes two state of the art Cirris testers configured to check up to 3200 points, customers can also specify voltage specific testing from 10 to 1500V.

A full record is kept of every automotive wiring harness we produce, giving you the peace of mind, it can be returned at any point for servicing, then tested to the same standard it was when first manufactured. We also offer our full 40-point quality control check procedure for 3rd party and in-service harnesses.

After our extensive 40-point test procedure we guarantee each wiring harness conforms to its exact specification and is ready to work straight out of the box.

Texense Sensors

Our partner company Texense, designs and manufactures World class, high accuracy embedded sensors. Texense has worked in close collaboration with some of the most innovative and prestigious brands, including, Ariane Space, Airbus and Ferrari.

Renvale’s association with Texense sensors dates back to the early 1990s. Destiny, as two of the World’s leading motorsport brands pull together to create a unified solution. A strong partnership that still remains today. We now represent ourselves globally, with offices in Europe, America and Asia, offering a valued reliable and trusted sensor and harness solution.

Texense products and services have been widely used and relied upon in various industries: Motorsport (from National Junior Series to World Championships such as Formula 1™, NASCAR™, IndyCar™, Moto GP™, Endurance and Rally), Aeronautic and Aerospace, Automotive Industry (Manufacturers, OEMS and Tier 1 Suppliers), Marine, Shipbuilding, and Railway Industries.

The Texense range includes a multitude of temperature sensors, aerodynamics and inertial sensors, through to CAN converters and force measurement systems. All are uniquely packaged with a winning combination of accuracy and reliability. Our dedicated strain gauging department relies on highly experienced technicians and the latest Instron tension/compression calibration equipment. We can provide a very high accuracy of ± 0.5% and a fast turn-around on parts.

Every Texense product has been used and tested in the highest levels of motorsport, one of the most punishing environments known to man, we can guarantee every Texense sensor will remain reliable and accurate in any application.

Situated in the same facility as Renvale is partner company Texys UK are sole UK distributors of Texense Sensors. Texys UK has recently partnered with micro-sensor manufacturer Sensorade and is now an official UK distributor. Sensorade designs and manufactures the world’s smallest most advanced pressure sensors. The products have been developed to integrate better within structures and offer less flow disruption during testing. For more information on Sensorade, please click here.
