A one-stop custom interconnect partner for OEM engineering teams
HiHarness designs and manufactures Form-Fit-Function equivalent connectors and complete custom cable assemblies. We help OEMs qualify a reliable second source, cut BOM cost, and shorten lead times without redesigning their hardware.

Engineering-led, quality-obsessed
From reverse-engineering a single sample to scaling scheduled production, our in-house engineering team owns wire selection, overmold tooling, shielding, and termination process — so every assembly drops into your existing design.
As a supply-chain integrator, we build through audited partner factories whose systems are certified to standards like ISO 9001, ISO 13485, and IATF 16949 — and we share those certificates for your qualification. Every harness we ship is built to IPC/WHMA-A-620 workmanship, 100% electrically tested, and traceable batch-by-batch through our ERP system.
