Manufacturing through our ISO 9001 certified China entity, Hebei Cloom Electronic Technology Co., Ltd., OurPCB delivers complete automotive wire harness and wiring solutions for vehicle electrical systems. Our wire harness expertise covers ECU harnesses, sensor cables, infotainment systems, and high-voltage EV battery harnesses supporting up to 1000V DC for electric mobility.
Modern vehicles contain complex electrical architectures requiring precise engine harnesses, dashboard wiring, and door harness assemblies. We supply Tier 1 and Tier 2 automotive suppliers with PPAP documentation, 100% electrical testing, and full lot traceability required for OEM production. Getting the automotive signal wire right — gauge, shielding and routing away from noise sources — is what protects sensor and data-bus integrity across the harness.
Electric vehicle growth demands specialized EV and new energy wire harness capabilities. Our battery wire harnesses support BMS connections, charging systems, and power distribution with proper shielding and IP67 protection. FAKRA and Mini FAKRA connectors serve antenna and camera applications.
Environmental testing validates harness performance across temperature extremes (-40°C to +125°C), vibration, and thermal cycling. Our testing capabilities include hipot, continuity, and functional verification. Waterproof assemblies and shielded cables protect sensitive automotive electronics.
Our 48-hour prototype service is available for simpler, ready-to-build automotive designs with available materials; exact timing is confirmed at quote. View our ISO 9001 certification for quality assurance details. Contact us for automotive wire harness quotes and PPAP support for your vehicle platform.
