Custom Wire Harness Manufacturing for OEM and Industrial Buyers
As a full-service custom wire harness assembly manufacturer, OurPCB transforms your design requirements into production-ready harness assemblies. Our wire harness services are tailored to your exact specifications, from unique connector configurations to specialized wire types and environmental protection requirements.
Our custom cable harness assembly capabilities span every industry and application. Whether you need automotive wire harness assemblies with ISO 9001 quality documentation, medical device cables with biocompatible materials, or industrial harnesses for harsh factory environments, we deliver customized assemblies that meet your exact requirements.
Our engineering team provides comprehensive design support from initial concept through production. We offer connector selection guidance, wire sizing calculations, routing optimization, and design for manufacturing (DFM) analysis. For projects without detailed drawings, we can work from concept descriptions, samples, or napkin sketches to develop complete harness documentation.
We support every harness type including waterproof sealed assemblies, EMI shielded cables, high-voltage harnesses, and continuous flex cables. Our component sourcing capabilities include all major connector manufacturers: TE Connectivity, Molex, Amphenol, JST, Hirose, and many more.
With 48-hour rapid prototyping and no minimum order quantity, you can validate your design before committing to production volumes. Our ISO 9001, and ISO 13485 certified facilities ensure consistent quality across industries including automotive, medical, industrial, and robotics.

Custom Harness FAQ
To provide an accurate quote, we need: drawings or schematics (if available), connector part numbers or requirements, wire specifications (gauge, color, length), quantity requirements, and any special requirements. We can also work from concept descriptions or samples if detailed drawings aren't available.
Yes, our engineering team can assist with harness design from concept to production. We offer connector selection, wire sizing calculations, routing optimization, and design for manufacturing (DFM) analysis. We can create drawings and documentation for customer approval.
We have no minimum order quantity. You can order as few as 1 piece for prototyping or small batches for testing. This allows you to validate your design before committing to larger volumes.
Lead times depend on complexity and quantity. Simple, ready-to-build prototypes with available materials can ship in 48 hours, with exact timing confirmed at quote. Standard custom harnesses typically take 2-3 weeks for production.
