Case Studies
The following projects showcase the breadth and depth of JDR’s wiring and electronics capability, from bespoke one-off loom builds to complex multi-system integrations on some of the most extraordinary cars in private ownership.
01
Porsche 993 GT3
Custom Wiring Loom
A private owner approached JDR requiring a complete custom wiring loom for their Porsche 993 GT3 competition car. The challenge was to design and build a bespoke loom that met the specific requirements of the car while retaining all original Porsche connectors throughout, preserving the integrity of the original vehicle architecture alongside the performance demands of a competition application.
JDR designed and assembled the loom at our facility in Essex, integrating all required systems while maintaining the original connector specification throughout. Following installation, the car was taken to Snetterton for a full circuit test, where it performed without issue.
Ferrari 456
Full Wiring and Electronics Build
A Ferrari 456 being prepared for competition in the Ferrari Club Classic series required a complete wiring solution from the ground up. JDR took on the full scope of the electrical build, including design and assembly of both the engine loom and chassis loom, ECU programming and setup, and installation and configuration of Power Distribution Modules (PDMs).
The project is a showcase example of the breadth of JDR’s electronics capability, from loom design and build through to full ECU and power management integration on a complex, high value competition car.

Caterham CT05
Formula Renault Engine Integration and Final Build
One of the more extraordinary private restoration projects in recent motorsport history, the Caterham CT05 is the 2014 Formula 1 car that was raced by Marcus Ericsson before the Caterham team went into administration. Acquired by a private owner and rebuilt over a number of years, the project involved integrating a Formula Renault engine and gearbox into the original F1 monocoque, an enormous engineering undertaking requiring bespoke fabrication, complex wiring and complete systems integration.
JDR completed the final stages of the build, including engine integration and the wiring loom and paddle shift system that brought the car to life. The car moved under its own power for the first time since the 2014 Hungarian Grand Prix, a moment the owner shared publicly alongside a direct acknowledgement of the JDR team’s work in completing the project.
