Thanks. Sorry I meant the air condenser switch, I thought it can request speed 2 independent of the rad switch? Track 45 in the diagram you posted. Is it possible for coolant temps to be below speed 1 so that the new fan is off, now the condenser can't request speed 2 of the old fan?
*edit* I get it now, it will request the new fan at its full speed! plus the old fan will be running at speed 1
