Plan, document and print professional wiring harnesses from your browser — no software to install, no spreadsheets, no guesswork.

The NDT Harness Planner is a cloud-based tool built specifically for motorsport and custom vehicle wiring. Whether you're building a full engine harness from scratch or documenting an existing one, it gives you a structured, visual way to plan every wire, connector and splice before you cut a single length of cable.

What you can do:

- Build pinout sheets for your ECU, PDU and other devices — assign functions, wire colours, wire sizes and lengths pin by pin
- Plan your harness topology with a visual branch diagram showing every junction, outgoing leg and connector splice
- Add autosport bulkhead connectors and Deutsch connectors with pre-loaded pinouts — wire lengths calculate automatically from your harness plan
- Generate a full materials list: wire lengths with cut allowances, sleeving, connectors and devices across every harness in your project
- Print clean, professional pinout sheets as PDFs — with your own company logo
- Run multiple projects simultaneously (multiple vehicles, multiple builds)
- Access your work from any device, anywhere

Wire colour coding with stripe support, ident markers for heat-shrink banding, real-time sync across connected pages, and a schematic view you can annotate and drag into the layout that suits your build.
