Create wiring diagram, SW?

Translated on 07-07-2026, 6:41.

Good evening.

I am looking for software to create wiring diagrams for the automotive sector.
The situation is relatively straightforward: a modified RX car with a racing engine control unit needs to be rewired, and proper documentation needs to be created for it (of course, with an RX car, there's not much to it in reality, but it's enough to confuse many people).

Since my search didn't yield any results, I hope you might have an idea.

Have a nice evening.

(I hope I've posted in the right forum.)

Hi,

sPlan 6.0 or TinyCAD 2.60.01...

Unfortunately, I haven't been able to test it myself due to lack of time.

Hello.

Thank you for the first response!

I've already tried quite a few things in the meantime, but the appearance of my plans still leaves a lot to be desired (they're definitely still far from the VW look).

What worries me the most is the labeling of the individual cables (color, cross-section).

Does anyone have any ideas for SPlan?

Thank you very much, and have a good evening.

It's a lot of work right now, but it will become easier when we get bigger/more projects.
Please provide the text you would like me to translate from German to English. I will then provide the translation without any explanations.
