What we can help with
Engineering support from first schematic to finished loom.
Whether you're developing a new electrical system or need to improve an existing loom, we can support the technical specification, sourcing and production route.
Existing loom review
Review and rationalisation of existing harnesses, including connector interfaces, serviceability and practical assembly issues.
Prototype harnesses
One-off and development looms for prototypes, machine upgrades and proof-of-concept equipment.
Low-volume production
Support for short runs and repeatable builds, without requiring a large initial order quantity to begin an enquiry.
Component sourcing
Practical support identifying compatible connectors, terminals, cable and other harness components.
Manufacturing coordination
Preparation of build information and coordination with suitable manufacturing partners where appropriate.
No-MOQ supply is subject to technical scope, suitable components, partner capacity and an agreed quotation. We do not promise every design can be built in a single unit.
Typical applications
Built around the real equipment.
Harness requirements vary significantly between projects. We support electrical integration across specialist applications.

How the process works
A practical route to a buildable wiring harness.
01 / REQUIREMENTS
Define the brief
Purpose, quantities, interfaces, environment, available drawings and timescales.
02 / ENGINEERING
Develop the design
Pinouts, conductor and connector choices, drawing packs and review of integration needs.
03 / PROTOTYPE
Review a sample
Where appropriate, build or source a prototype and verify fit and electrical function.
04 / PRODUCTION
Prepare for supply
Agree the build specification, inspection expectations and repeatable production plan.
Frequently asked questions
Wiring harness enquiries.
Is there a minimum order quantity?
No-MOQ enquiries are welcome, including single prototypes. Availability and pricing depend on the design, parts, production route and quotation.
Can you design a loom without existing drawings?
Yes, subject to a suitable requirements and discovery process. We can work from available information about connectors, electrical interfaces, equipment and intended operation.
Can you review or reproduce an existing wiring loom?
We can review existing assemblies and investigate replacement or redesign options. Feasibility depends on the condition and accessibility of the original, component availability and any relevant rights or permissions.
Do you supply just harnesses, or can you help with the whole electrical system?
We can also help with machine electrical architecture, electronics, battery integration, controls and related engineering work where appropriate.
Start your project
Need a wiring harness designed or produced?
Tell us the equipment, required quantity and approximate timescale. Drawings, photographs, connector information or an existing sample are useful, but you don't need a complete technical specification to start a discussion.
Please avoid sending confidential or proprietary materials until an appropriate confidentiality arrangement is in place.
