Replaced the water-heater yesterday - replaced with identical unit as original (Suburban SW6D).  While at it, installed an indicator light that lets me know when the unit is actually heating water.  Green wire, from switch, is negative (ground); brown wire, from controller*, is +12v when the unit is heating.  Tapped into both these wires and connected to a LED indicator ($10 at Auto-Zone).  Will be nice to know when the heater is finished after showers and washing dishes.
