# Zorowire

> Wire-harness documentation and quoting software for small harness and cable-assembly shops. Enter a harness once (connectors, pinouts, wires, branch lengths, coverings) and get the 1:1 formboard drawing, the wire cut list, the BOM and the quote; a change updates all of them. Runs in the browser. Free plan: unlimited harnesses up to 150 connections each, 3 quotes a month, no card, no watermark.

## Guides
- [How to quote a wire harness: material, labour, setup, margin](https://zorowire.com/guides/how-to-quote-a-wire-harness): Quote a harness as material (BOM × your prices + scrap) + labour (each operation counted from the harness × your time for it × your hourly rate) + setup divided over the batch + one-off NRE + margin.
- [Wire harness RFQ checklist: what to get before you quote](https://zorowire.com/guides/wire-harness-rfq-checklist): Before quoting, make sure you have the drawing with its revision, the connection list, a BOM with manufacturer part numbers (and allowed alternates), quantities and delivery, wire, covering and marking specifications, test requirements and the acceptance standard the customer names.
- [Labour times for wire harness work: crimp, insert, tape, test](https://zorowire.com/guides/labour-times-for-harness-work): There is no open, citable standard for harness labour times.
- [How to calculate wire cut lengths from branch lengths](https://zorowire.com/guides/how-to-calculate-wire-cut-lengths): A wire's cut length is the sum of the branch lengths along its route, plus an allowance at each end (from the dimension point to the end of the terminal, strip length included), plus any service loop, then slack or twist take-up, rounded up.
- [Strip lengths for crimp terminals: where to find the right value](https://zorowire.com/guides/strip-lengths-for-wire-harnesses): There is no single correct strip length: it depends on the terminal and the wire size, and the terminal maker gives it in the terminal's application specification.
- [Revision control for wire harnesses: one change, every document](https://zorowire.com/guides/wire-harness-revision-control): Freeze each revision, give every connector and wire a stable ID that survives renaming, and derive the cut list, BOM, board and quote from the revision instead of editing each one.
- [Cable assemblies vs wire harnesses: what changes for the shop](https://zorowire.com/guides/cable-assemblies-vs-wire-harnesses): A wire harness is a set of wires and connectors bundled to a fixed, usually branched shape and built on a formboard.
- [A cut-list CSV your wire-processing machine can import](https://zorowire.com/guides/cut-list-csv-for-wire-processing-machines): Neither Komax nor Schleuniger publishes a cut-list file format.
- [A from-to list in Excel that imports without retyping](https://zorowire.com/guides/wire-harness-from-to-list-in-excel): Keep one row per wire with a header row: wire, from, to (or from connector + from pin, to connector + to pin), cross-section, colour and length.
- [How to print a formboard at 1:1 (and check that you did)](https://zorowire.com/guides/print-a-formboard-at-full-scale): Print at 100 % or “Actual size”, never “Fit” or “Shrink”, then measure the 100 mm check ruler on the page.
- [Wire gauge: AWG to mm² and back, for harness work](https://zorowire.com/guides/wire-gauge-awg-to-mm2): AWG sizes convert to mm² through the AWG definition: diameter d = 0.127 × 92^((36 − n)/39) mm, area = π·d²/4.
- [Wire colour codes: IEC 60757, DIN 47100 and how lists write them](https://zorowire.com/guides/wire-colour-codes): Most harness lists use the IEC 60757 two-letter codes: BK black, BN brown, RD red, OG orange, YE yellow, GN green, BU blue, VT violet, GY grey, WH white, PK pink, TQ turquoise, GNYE green-yellow.
- [Choosing a fuse for a wire: the checks, step by step](https://zorowire.com/guides/choosing-a-fuse-for-a-wire): The fuse protects the wire.
- [Voltage drop in wire harnesses: formula, limits, example](https://zorowire.com/guides/voltage-drop-in-wire-harnesses): Voltage drop is Vd = I × R′₂₀ × (1 + 0.00393 × (T − 20)) × L, with R′₂₀ the wire's resistance per metre at 20 °C, T the conductor temperature and L the loop length (feed plus return).
