A couple of quick Q's about a 2004 2nd Gen Prius - brakes and engine use....

Hi guys,
I'm looking for a quick way to tell if my gasoline engine is running or not.
I've found that the MFD display is not always accurate on that point.

What I want to do is rig up a simple set of lights or LED lights on my dash to indicate two
simple things for me;

- whenever my gasoline engine is on and running

and

-whenever my friction brakes are engaging as opposed to just the regenerative back braking
from the generator. I cannot tell the difference between the two and when they are happening.

My 2004 seemingly has no define way of indicating that to me.
Is there a simple way to tap into the wiring and rig an indicator lamp for these two things?

thanks,
