NDT Wiring Harness Planner - Subscription Service

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. Design a new harness from scratch or document an existing one with a structured, visual workflow that helps you plan every wire, connector, splice and branch before cutting cable.

What you can do:

• Build pinout sheets for ECUs, PDUs and other devices, including functions, wire colours, wire sizes and lengths
• Plan harness topology with a visual branch diagram showing junctions, outgoing legs, connectors and splices
• Add autosport bulkhead and Deutsch connectors with pre-loaded pinouts and automatic wire-length calculations
• Generate complete materials lists, including wire lengths with cut allowances, sleeving, connectors and devices
• Print clean, professional PDF pinout sheets with your own company logo
• Manage multiple projects and harnesses at once
• Access your work from any device, anywhere
• Use wire colour coding with stripe support, ident markers for heat-shrink banding, real-time sync and an annotatable schematic view
