Custom Wire Harness
YOUR DRAWING.
OUR FIXTURE BOARD.
FAST RFQ REVIEW.
Drawing-driven custom wire harness assembly from the Cavite, Philippines plant. Send the drawing, BOM, sample photos, connector list, and approved-vendor constraints so engineering can review the build package before prototype or production release.

China+1 / Cavite, Philippines
Build custom wire harnesses outside mainland China.
XUDONG is a Philippines-based contract manufacturer for buyers who need wire harness and cable assembly production with English-friendly export support, non-mainland-China supply diversification, and a fast RFQ path from the Cavite engineering desk.
Where we produce
Cavite, Philippines: a China+1 manufacturing base outside mainland China for US-bound interconnect programs.
Why US buyers care
Reduce China-sourcing exposure, tariff risk, and single-country dependency while keeping competitive Asian cost.
What we make
Custom wire harness assembly and integration from drawings, BOMs, connector lists, samples, and target volumes.
What to send
Drawings, BOM, samples, target annual volume, and any current supplier constraints.

What “Custom” Means Here
DRAWING-DRIVEN.
NOT CATALOG-DRIVEN.
The Cavite plant focuses on made-to-print custom wire harness assembly. We do not stock a catalog of pre-made parts or sell raw wire and loose connectors as a distributor. Each program starts from a customer DXF, PDF, BOM, sample, or connector list and moves through engineering review before release.
The four sibling pages — waterproof, high-voltage, overmolded, and prototype / NPI — are not separate factories. They are the same custom build with one extra constraint stacked on top. Send your drawing here when sealing, voltage and overmold are not the binding constraint; otherwise route to the matching sibling page.
Capability Block
WHAT THE CUSTOM
LINE DELIVERS.
Custom Layouts From Your Drawing
Signal, power, control, multi-branch, and mixed-gauge harnesses are assembled from customer drawings, BOMs, samples, and approved revision packages.
Cross-Brand Connector Library
Molex, TE, JST, Amphenol, Hirose, JAE, Sumitomo, Deutsch, and other connector families can be reviewed against your approved-vendor list and drawing requirements.
Controlled Crimping Workflow
Crimp setup, terminal fit, insulation support, visual inspection, and pull or cross-section checks are planned around the drawing, terminal specification, and customer acceptance criteria.
Wire Vendor Flexibility
Customer-approved wire, cable, sleeve, label, and protection materials can be sourced to the released BOM. XUDONG is a contract assembler, not a raw-material distributor.
Electrical And Visual Inspection
Continuity, polarity, connector orientation, labeling, workmanship, and packaging checks are configured to the customer drawing and inspection plan.
Program Documentation Support
Process flow, control plan, first-article records, material traceability, and customer-specific production documents can be prepared when they are required by the program.
