The blue (or white) wire is the relay trigger wire for the fridge when it is
on DC power.  It will trigger the relay so that power to the fridge when on
DC is only provided when the engine is running.  This is used when you only
have a start battery and no aux battery and you don�t want to have a dead
battery out in the boondocks.
