Jim,

    While addition of any component adds complexity and additional 
opportunities for failure, we also have to look at the failure modes.  If the 
additional wiring is done well, shorts and opens of the actual wire should be 
nil.
That leaves the switch - two failure modes, stuck open and stuck shorted.  If 
it's stuck open, the controller has the same lag that's being experienced now. 
  If it's stuck closed, the pump will run all the time until you land and 
disconnect it.  I wouldn't think that either event is a flight stopper.
