When I installed the flow through Airtex E8902, I wired mine to the map lite switch. When the switch is on the light is on and so is the fuel pump. When the ignition is off the switch is dead. I use the mechanical pump 99% of the time. Only use it to fill the float bowl after the car has sat for a lengthy period of time, or to clear vapor lock bubbles. (picture 2)
