01
Push electrical data
Wire lists, gauges, and connector mappings flow from WireIt into your Onshape assembly through a direct API integration.
02
Route in 3D
Path harness bundles through your enclosure using Onshape Wire features — real clearances, real bends, real geometry.
03
Sync lengths back
Measured 3D cable lengths flow back into WireIt. Cut lists and BOMs update with actual routed distances — no tape measure.

What Is Wire Harness Design Software?
Wire harness design software is a specialized engineering tool for creating, documenting, and managing electrical wiring harness assemblies. Unlike general-purpose CAD, it understands connectors, pin assignments, wire gauges, signal routing, and the manufacturing documentation needed to prepare harnesses for review.
Engineers use wire harness design software to generate schematics, bills of materials, wire cut lists, connector pinout diagrams, and harness topology drawings — replacing error-prone spreadsheets and disconnected tools with a single source of truth that stays accurate from first concept through factory handoff.
Why Engineers Choose WireIt
WireIt is wire harness design software for engineers who need clearer handoff outputs without weeks of manual documentation. Design your electrical system, and WireIt keeps BOMs, cut lists, and connector pinout tables aligned as you work. Teams can also start from existing KiCad or Altium work and bring in existing wire lists before moving into BOMs, cutlists, and documentation packages. With round-trip 3D integration through Onshape, you can push wire data into your MCAD assembly, route cables in 3D, and sync actual measured lengths back into WireIt.
WireIt supports both cloud and on-premises deployment including air-gapped environments. Whether you are a solo engineer or an enterprise team, WireIt scales from single-sheet designs to complex multi-harness systems with cross-sheet net management and real-time design rule checking.
Import Existing Design Data
Teams rarely start from a blank page. WireIt helps bring existing KiCad, Altium, and wire-list work into WireIt designs.
