Engineered Connections for New-Energy Mobility
Four program families. One disciplined engineering path.
Instead of selecting an off-the-shelf part, buyers start with the vehicle or equipment architecture, then define interfaces, routing and validation requirements with our team.
Customer drawings, BOMs and interface definitions remain the source of truth throughout sampling and production planning.
Vehicle Electrical Distribution Systems
Build-to-drawing high- and low-voltage harness assemblies for complete vehicle electrical distribution.
L4 Autonomous Logistics Harness Systems
Integrated power, control and signal harness programs for last-mile autonomous delivery platforms.
Smart Cockpit & Seat Harness Systems
Seat and cockpit wiring solutions connecting comfort, safety and adjustment functions.
Custom Harness Engineering
Application-specific assemblies for robotics, drones, energy storage and industrial machinery.
Four markets, each with a different electrical architecture
We map power, signal, packaging and verification needs to the operating platform—not to a generic catalog.
From Your Drawing to a Documented, Production-Ready Harness
A focused sequence for build-to-drawing and OEM/ODM programs, from first review to production progress updates.
- 01
Drawing & Requirement Review
Share your drawing, specification, and application context so our engineering team can scope the program.
- 02
Build-to-Drawing Engineering
Harness construction, routing, and terminal placement are engineered to your specification, including OEM/ODM programs.
- 03
Sampling
Samples are produced for your team to validate fit, routing, and function before production is scheduled.
- 04
Documentation & Inspection
Technical and test documentation is prepared, with third-party inspection support coordinated where requested.
- 05
Production & Progress Updates
Production runs on our semi-automatic harness lines, with progress updates provided to keep your team informed.

A focused manufacturing partner for custom harness programs
Henryun Optoelectronic Technology (Zhejiang) Co., Ltd. is structured around one objective: turning your drawings into reliable, production-ready wiring harnesses.
Build-to-Drawing Engineering
We work directly from your drawings and specifications, translating engineering input into a manufacturable harness design.
High- and Low-Voltage Under One Roof
A single supplier for both high-voltage and low-voltage harness programs, reducing coordination overhead across your supply chain.
Structured Production Lines
Three semi-automatic high-voltage lines and six semi-automatic low-voltage lines support consistent, process-controlled output.
Documented Testing Support
Technical and test documentation, plus support for third-party inspection, so your program has the paper trail it needs.
