What amp's are the WOT switch's included in the kits rated for?
I'll have to double check on that, but I THINK anywhere from 12 to 15 amps.
instructions say to wire on pulsoid earth side
They can be wired on the positive side as well; I've done so in the past with no ill effects.
Looking to wire mine as per attached picture, but only single stage 1 relay
I gather you are using a megasquirt unit to trigger the nitrous system? In that case it will work as if it were any other solenoid pair. Be sure you use a relay capable of handling the load. The current requirements of the pulsoids differ among higher flowing units: increasing current with increasing flow capacities.
