What is the difference between a wire harness and a cable assembly?

A wire harness bundles many wires and branches for internal routing; a cable assembly is typically a single finished cable with connectors at each end.

What standards do you build harnesses to?

IPC/WHMA-A-620 workmanship, with 100% electrical testing.

Can you build automotive harnesses?

Yes, with sealed connectors and protective sleeving — and automotive programs build through IATF 16949-certified partners.

How do I order a custom wire harness?

Send a wiring diagram or BOM, connector types, wire gauges and lengths, and protection requirements — or a sample to reverse-engineer.

We can start with small trial quantities because we are the factory.

Are they RoHS compliant?

Yes, we use RoHS-compliant wire and connectors.

Custom Wire Harness Manufacturer

Custom wire harness manufacturer — Automotive & industrial cable assemblies with JST/Molex connectors. 100% tested. OEM wire harness factory in China.

What is a Wire Harness?

A wire harness — also called a wiring harness or cable loom — bundles many wires and connectors into one organized assembly that routes power and signals through a machine, vehicle, or appliance. It turns a tangle of individual wires into a single, installable, serviceable component.

What We Build

Automotive and industrial harnesses with sealed connectors and protective sleeving.
Custom pinouts and multi-branch layouts to your wiring diagram.
Labeling, heat-shrink, and loom protection for production-ready installation.

Materials and Quality

We use UL-listed wire, self-manufactured connectors, and 100% electrical testing. Harnesses are built to IPC/WHMA-A-620 workmanship standards — the benchmark for wire harness quality. For automotive programs we build through IATF 16949-certified manufacturing partners, the quality management standard the automotive supply chain requires.

Applications

Wire harnesses are used in automotive, industrial machinery, appliances, medical equipment, and control panels.

How to Order a Wire Harness

Provide a wiring diagram or BOM, the connector and terminal types, the wire gauges and lengths, and any protection or labeling. Send a sample and we reverse-engineer the harness to spec.

Custom Harnesses & OEM/ODM

As a factory with in-house connectors and crimping, we deliver custom harnesses at competitive cost and short lead time, and can scale from prototypes to volume production.
