Wire harness design software
Wire harness design software with digital work instructions and instant quoting
Harnessora is wire harness design software for US contract manufacturers. Your engineer draws the harness once — Harnessora generates the digital work instructions, the instant quote, the bill of materials, the formboard, and the wire cut list from that single drawing.
One drawing, five outputs
Draw the harness once. Harnessora generates five documents your whole team works from — digital work instructions and the instant quote lead, followed by the BOM, the formboard, and the wire cut list.

Digital work instructions
On-screen instructions for building the harness and routing wires on the formboard.

Instant quote
A quote generated from the same harness drawing.

Bill of Materials (BOM)
A component and material list generated from the harness drawing.

Formboard
A formboard layout generated from the harness drawing for assembly and wire routing.

Wire cut list
A wire preparation list generated from drawing data.

Component library
Built-in component library with manufacturer-guided selection
Work with connectors, terminals, seals, accessories and loom in one built-in library. Harnessora automatically selects compatible terminals and seals using recorded manufacturer recommendations for supported components.
The library supports design and component selection. Work instructions, instant quote, BOM, formboard, and wire cut list remain the five outputs generated from the drawing.

Draw → Generate → Instant Quote → Prepare → Build & Route
Generate is the software at work. The stages around it are your people — the estimator quoting from drawing-derived information, preparation cutting to the drawn lengths, and the shop building from the formboard with on-screen work instructions.
Draw
The engineer creates the harness drawing.
Harness engineer
Generate
Harnessora derives the five outputs from the drawing.

Instant quote
The estimator uses drawing-derived information in the quote.
Estimator
Prepare
Preparation cuts wire to the drawn lengths from the cut list.
Wire preparation
Build & route
The shop builds the harness from the formboard and on-screen work instructions.

Follow one harness through the process
Here is one harness drawing. Watch the same connectors and wires — J1 through J4, W1 through W8 — carry into every output Harnessora generates from it.
Illustrative example: HAR-EX-101 (drawing rev B)
Illustrative exampleA small industrial control-panel accessory harness: four connectors, eight wires, and one branch.

| J2 | Rectangular connector, 8-position | 8 | 5 |
| J3 | Rectangular connector, 6-position | 6 | 3 |
| J4 | Rectangular connector, 4-position | 4 | 2 |

Why the shared drawing matters
In many shops, the same engineering information gets re-entered into each downstream document — the BOM, the cut list, the formboard artwork, the instructions. Every re-entry is another chance for the documents to drift apart from each other and from the drawing the customer approved.
One source of truth
Every output derives from the same drawing, so the shop builds what the engineer drew and the customer saw.
Less repeated entry
Component and wire information is entered when the harness is drawn, not re-typed into each document that needs it.
Consistent documents
BOM, cut list, formboard, and instructions generated from one drawing can stay consistent with each other, rather than maintained as separate hand-maintained files.
Who uses Harnessora
Built for US wire harness and cable assembly contract manufacturers — including build-to-print shops — and for the people inside them who do the work.
Harness engineer
One drawing instead of many disconnected documents: the connector pinouts, wire list, and lengths live in one place, and the five outputs derive from it.
Estimator
Drawing-derived component and wire information for the quote, so the estimate starts from the same engineering facts the shop will build from.
Production manager
A consistent set of manufacturing documents — formboard, cut list, and work instructions — generated from the same drawing the estimator quoted from.
Assembly operator
On-screen work instructions for routing wires on the formboard, generated from the drawing rather than hand-copied from a print.
Owner
A single source of engineering information from drawing through quote and build, so the documents the shop uses match the documents the customer approved.
