EDIT - I hit send before I should have - Paul's code new restricts regen to disengage at 0 rpm for forward. That part is done and working.

So - to review:

button	brake	description
Off	Off 	normal forward controlled by accelerator pedal
Off	On	normal forward but using friction brake pads using hydraulic 
		pressure from how far the brake is pressed
On	On	regen braking as well as friction braking.  I'm not sure how 
		much regen braking when you press the button, or if it 
		increases as you hold the button

Now, we'll add the low rpm - like maybe 50 rpm or something

button	brake	description
Off	Off 	normal forward controlled by accelerator pedal
Off	On	assuming we're stopped below 50 rpm
On	On	assuming we're stopped below 50 rpm, change to reverse.  
		But the throttle works in reverse as long as you don't have 
		the brake pedal to the floor?
Off	On	assuming we're stopped below 50 rpm, after going reverse
Off	Off	back to normal operation in forward

This description assumes no regen braking without pressing the brake pedal and having that switch enable the regen/reverse button on the dash, or steering wheel, or whatever. That is what you meant by

just running the source ground through the brake switch before going to the reverse switch?

I think we're getting close to a description that would be required by anyone who takes on the programming mods ...
