I wish the MFR would have thought of that!  Problem is the few feet of
wiring is integrated into the unit.  So the closest the diode could
get would be the terminals - one end of the solenoid is already
internally tied to +12V (can't be changed).  So... best I can do is
put a diode from +12 to the solenoid power input.  But then it
interferes with the whole reverse polarity protection I want to put
onto the circuit that drives it.
