Custom Wire Harness & Cable Assembly Manufacturers
When your product depends on the cable, the build has to be right. P&A International designs, prototypes and delivers custom cable assemblies and wire harnesses — cable assemblies, multi-branch harnesses, ribbon/IDC and overmoulded USB-C — built to your connectors, wire gauge, routing and test requirement.
As an engineering-led contract manufacturer founded as an engineering consultancy, we put one dedicated engineer on your project from drawing review to qualified, tested samples in 10–15 working days, then scale into volume through our vetted partner-factory network, where every supplier is ISO 9000 certified or better.

Cables & harnesses we make
Custom cable assemblies
Single- and multi-conductor cable assemblies built to your connectors, length and rating.
Wire harnesses
Multi-branch harnesses with breakouts, labels and the right terminals for your assembly.
Ribbon & flat cables
IDC ribbon and flat-flex for compact board-to-board and internal interconnects.
Overmoulded & USB-C cables
Overmoulded power and data cables, including USB-C / USB-PD, for robust field use.
Need the boards or power supplies these cables connect to? We also build flexible PCBs, electronics assembly and custom power supplies through the same engineering team and partner network.
Engineering capability
- Build from your wiring diagram, netlist or a sample to copy
- Connector and contact selection, crimp vs IDC, and pre-tinning
- Wire gauge, insulation and colour-code selection for current and flex life
- Sleeving, braid, conduit, tape, heat-shrink and strain-relief design
- Overmoulding and potting for sealed, robust terminations
- Continuity and hipot test; build to IPC/WHMA-A-620 Class 1/2/3
- DFM review to hit target cost while preserving reliability
- One dedicated engineer owns the project end-to-end

Why engineers & buyers choose PA
For design engineers
A true build partner — one dedicated engineer, connector and crimp selection, routing and strain-relief design, and DFM that catches field-reliability risks before tooling. We build to your drawing or sample, not a generic catalogue.
For purchasing
Low-risk scalability — predictable 10–15-day prototypes, flexible MOQ from one-off to production, target-cost DFM, a single point of contact, and a vetted ISO 9000+ partner network managed end-to-end by P&A. No hand-offs, no surprises.
3 easy steps to get started
Send us your drawing
Send your wiring diagram, connector list or a sample. One dedicated engineer reviews it and confirms the build with you.
Proposed build & quote
You receive a proposed build and indicative pricing — typically within 48 hours — to review and refine together.
Samples & production
Qualified, tested samples in 10–15 working days; on approval we scale into volume through our partner network.
Applications
Industrial machinery & automation · medical devices · instrumentation & test · automotive & e-mobility · consumer electronics · networking & telecoms · energy & storage systems.
See our main wiring harness manufacturing page, plus electronics contract manufacturing, flexible PCB and custom power supplies.
Choosing the right cable or harness
Getting the build right early avoids costly field failures. A few decisions shape every cable assembly — and sharing this detail lets us quote and prototype faster:
| Build type | Single cable assembly, multi-branch harness, ribbon/IDC, or an overmoulded cable — tell us the application and we recommend. |
| Wire & terminal | AWG, insulation and rating set current capacity and flexibility; matching the right terminal/crimp to the contact is the key reliability driver. |
| Protection | Sleeving, braid, conduit, tape and heat-shrink for abrasion, EMI and flex life; strain relief where the cable meets connectors. |
| Test & class | Continuity and hipot as standard; IPC/WHMA-A-620 Class 1/2/3 to match the product reliability need. |
| Environment | Temperature, vibration, moisture/IP and any automotive or medical requirement drive material and overmould choices. |
What to send us for a fast, accurate quote
The more of this you can share, the quicker we can return a proposed build and price:
- Wiring diagram / harness drawing, or a sample to copy
- Connector make & series at each end (or function)
- Wire gauge (AWG), insulation, colour-code and rating
- Circuit count, overall length and branch/breakout dimensions
- Terminals/contacts, crimp vs IDC, pre-tinning
- Sleeving, braid, conduit, tape, heat-shrink, labels, strain relief
- Test requirement (continuity/hipot/pull) and IPC/WHMA-A-620 class
- Operating environment and target cost, quantity and annual volume
Working from a sample or a competitor part is fine — our engineer will reverse-engineer it or build a drop-in equivalent to your specification.
