Special Wire Harness
Special Wire Harness Assemblies Built to Your Drawing
Dongguan Songyuan Technology Co., Ltd. manufactures a broad range of cable and harness products, and our special wire harness line covers assemblies that fall outside standard catalog constructions. If your project calls for a non-standard conductor arrangement, shielding, jacket material, or connector combination, our engineering and production teams can review your drawing and build to it.
We have operated our own 2,000 sqm factory since 2017, with 60 employees across four defined areas: harness production, wire drawing and extrusion, quality inspection, and warehouse and shipping. That in-house structure lets us control each stage of a special wire harness build rather than passing it between outside suppliers.
What Counts as a Special Wire Harness
A special wire harness is generally a cable assembly specified by the customer rather than selected from a catalog. Typical reasons a buyer needs one include:
- A connector or termination combination not available as a standard part
- A specific shielding or jacketing requirement
- A cable construction matched to a particular routing or environment
- A build that combines wires and cables with custom breakout lengths
Because each special wire harness is defined by the customer's own specification, we do not publish fixed electrical or dimensional parameters for this category. Share your drawing, sample, or requirement description and we will confirm what we can build.
Applications We Serve
Our manufacturing scope covers wire harnesses and cable assemblies for consumer electronics, industrial control, medical, energy storage, new energy, and hydrogen energy applications, as well as military-grade cable assemblies. Special wire harness work often sits at the intersection of these areas — for example, an industrial control panel requiring a non-standard breakout, or a new energy storage system needing a specific shielded power cable assembly. Wires and cables, including shielded power cables and ribbon cables, are also produced in-house.

Prototyping and Order Quantities
Prototyping lead time is 48 hours for standard specifications. Flexible order quantities are available — prototype runs from 100 pcs, volume production from 1,000 pcs. For mass production, typical shipping timelines run 15–25 days. Certificates available upon request.
We exhibited at NCH2025, the Shanghai International New Energy Connector and Wire Harness Processing Technology Exhibition, and we serve customers across Southeast Asia.
