Free Wiring Schematic Creator?

[motorsportbeng]

Hi all,

I'm currently building/designing the basic wiring loom for my track/circuit car and was wondering if anyone has any experience of any free online tools/software that will allow you to create a basic wiring schematic that I can save as a PDF or similar. Something neat and easy to keep safe to help me in the future when I no doubt forgot what I had design or to pass onto the next owner should I come to sell the car etc.

I don't need anything fancy, just basic block diagrams with switches etc. and straight lines to represent wires to replace the scribbles that I've currently got on various bits of paper!

Cheers!

There's a bunch of them which are all very similar, free and browser-based.

...however I use DoCircuits purely because for £25ish a year their platform can work offline as a standalone app - which means I can work on my commute.
