XC40 Wiring Explorer mini app - iGeorge3 - 08-11-2026
Hi everyone,
I’ve put together a small interactive Volvo XC40 wiring-diagram explorer and thought it might be useful to share here.
It lets you click components, connectors, wires, and pins; trace branches or full geometry; show wire colours; and follow ordered routes through connectors. It’s still a public preview, so I’d really appreciate feedback, especially if you find an incorrect pin, route, colour, or missing branch.
I should be transparent: I have limited coding experience, and this was built entirely with Codex. I hope it can still be useful for troubleshooting and understanding the XC40 wiring diagrams.
I built it mainly because I had to go from Peugeot/citroën/DS drawings which were fully interactive in Servicebox to PDF diagrams for my XC40, and I wanted something more interacttive for my projects.
Download / source page: https://github.com/igeorge39/XC40-Wiring-Explorer
Windows users only need to download and run the EXE, no Python or other installation is needed. Please read the README before sharing further, as the included wiring document has its own copyright/distribution notice.
Thanks, and I’d love to hear what people think.

I didn something similar but for the whole CMA plattform but focused on the PS2 , did the mapping manually and let Claude Fable do an interface (wanted to test out if it was as good as people said)
Idea behind it was for troubleshooting retrofitting https://lighthearted-babka-421119.netlify.app/
I'll buy a proper domain if it's actually useful for people

Nice well done

That was my initial idea, indeed!
Then Codex gave me the idea of keeping it as a PDF and highlighting it.
But perhaps as a V2 I'll be redoing it in this way as a website indeed!
Nice work for the PS2 drawings though! It should be almost the same as the XC40 since they're pretty much the same car with different body

I can open source if you want and you can keep building on it, I dont really have time currently to do what I want.
Plan is add support for SPA cars but also comparing between model years so if you want to retrofit stuff between 2021 and 2026 you would see the diffrence via overlay
XC/EX40/C40/Polestar 2 are 100% identical electrically

IF you'd like to make it open source, then why not! Perhaps on github and even if I don't have time to do it, perhaps others will
