Can the Fusion brain "monitor" the button without feeding voltage back into it?

Is it something I should even worry about?

You would have to use an analogue input. Which I prefer anyways.

But then connect the "interesting" button wire (2v->GND) to the analogue input. No voltage will be fed out, and it should register as long as you ground the Brain to the chassis as all car installs will be.

If you use a digital input, it wont register because it needs to be 5v to trigger.
