Custom Wiring Harness & Cable Assembly Manufacturer
Reliable interconnects keep your product working in the field. P&A International engineers, prototypes and delivers custom wiring harnesses and cable assemblies — multi-branch harnesses, cable assemblies, ribbon/IDC and overmoulded USB-C — built exactly to your connectors, wire gauge, routing and test requirement.
As an engineering-led contract manufacturer founded as an engineering consultancy, we assign one dedicated engineer to 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.

Harnesses & cables we make
Custom wire harnesses
Multi-branch harnesses built to your wiring diagram — connectors, gauges, breakouts and labels to spec.
Cable assemblies
Single- and multi-conductor cable assemblies with the right terminals, crimps and strain relief.
Ribbon & flat cables
IDC ribbon and flat-flex assemblies for board-to-board and internal interconnects.
Overmoulded & USB-C cables
Overmoulded power and data cables, including USB-C / USB-PD, for robust field connections.
Need the boards these cables connect to as well? We also build flexible PCBs and electronics assembly 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, 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

Choosing the right harness or cable
Getting the build right early avoids costly field failures. A few decisions shape every harness — 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. |
IPC/WHMA-A-620 class quick guide
| Class 1 | General electronic products — basic function |
| Class 2 | Dedicated-service products — continued performance and extended life |
| Class 3 | High-reliability — medical, aerospace, automotive safety (no field downtime) |
| Test as standard | continuity + hipot; add pull-test to the chosen class |
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.
