Bespoke Test Rigs & Engineering Equipment

Breakout harness, switch box or a complete ECU test bench, we build the rig your programme runs on.

When off-the-shelf kit can't reach the signals or run the test you need, we design and build something that can.

Off-the-shelf equipment doesn't always fit the job

Engineering teams often face situations where:

  • Existing tools don't provide access to the signals they need

  • Testing requires a unique vehicle configuration

  • Multiple systems need to be integrated together

  • Data logging equipment needs custom interfaces

  • Prototype vehicles require specialist harnesses

  • Manual testing is taking too much time

When standard equipment becomes a limitation, a bespoke solution can remove the bottleneck.

How We Work

From initial concept through to delivery, we follow a structured approach to ensure every bespoke solution is practical, reliable and ready for real-world testing.

01

Understand the Challenge

We start by understanding your objectives, existing limitations, vehicle architecture, testing requirements and project timescales.

02

Design the Solution

Our engineers develop a practical design focused on functionality, reliability, ease of use and future scalability.

03

Build & Validate

Every rig, harness or piece of equipment is assembled, tested and verified before delivery to ensure it performs as intended.

04

Support & Evolve

As requirements change, we can modify, expand or enhance your solution to support future testing activities and programme developments.

Example Applications

From prototype development through to production validation, our bespoke equipment is designed around the challenges engineering teams face every day.

🚗

Prototype Vehicle Development

Create access to signals, networks and modules that would otherwise be difficult to monitor during development programmes.

🔗

System Integration Testing

Build dedicated test environments for validating ECU interactions, network behaviour and feature functionality.

💻

Diagnostics Development

Create repeatable testing environments for diagnostic routines, software updates and validation activities.

🎓

Training Environments

Develop practical demonstration and training rigs that allow engineers to learn on realistic systems.

🏭

Production Testing

Design repeatable test systems for manufacturing, end-of-line validation and quality assurance processes.

📊

Data Acquisition

Capture critical vehicle and system data through bespoke interfaces, breakout systems and logging solutions.

Why VTS?

Most suppliers ship you a box. Our engineers help you work out what to build, build it, then change it when your programme moves on.

01

Engineering-Led

Every solution is designed by engineers who understand vehicle testing, diagnostics and systems integration.

02

Built Around Your Requirement

We design equipment around your testing challenge rather than forcing you into an off-the-shelf solution.

03

Fast & Flexible

Prototype programmes move quickly. Our team can adapt designs, modify equipment and respond to changing requirements.

04

Real-World Experience

Built on years of supporting OEMs and suppliers with electrical systems testing, validation and integration activities.

Frequently Asked Questions

Common questions about our bespoke test rigs, wiring harnesses and custom engineering equipment.

Can VTS design and build a test rig from scratch?

Yes. We can help turn a testing requirement into a practical rig, bench setup or bespoke piece of equipment.

Do you only build automotive test rigs?

Our core experience is automotive electrical systems testing, but many of the same principles apply to off-highway, commercial vehicle and specialist equipment projects.

Can you build bespoke wiring harnesses?

Yes. We build low-volume custom harnesses, including breakout harnesses, inline harnesses, diagnostic leads and data logger interfaces.

Can you work from wiring diagrams?

Yes. We can work from wiring diagrams, pinout information, connector details or existing hardware, depending on what is available.

Can you help if we do not know exactly what we need?

Yes. You can explain what you are trying to test, measure or access, and we can help define the right solution.

Do you test the equipment before delivery?

Yes. Bespoke equipment is built, checked and validated before it is supplied.

Can you modify an existing rig or harness?

Yes. We can support updates, adaptations and improvements as project requirements change.

What types of equipment can you create?

Examples include ECU test benches, desktop rigs, breakout boxes, switch boxes, CAN access harnesses, diagnostic interfaces and data logger integration solutions.

Is this suitable for prototype development?

Yes. This service is especially useful for prototype vehicles, development rigs, early validation work and short-run engineering projects.

How do we start?

Send us your requirement, wiring information, photos, drawings or a description of the challenge, and we can advise on the next step.
