should a s4 injector have 12v or does the resister drop them down to 6v?

thats a good one! since the resistor pack is on the ground side, imma say 12v

BUT THE RESISTER IS POWER THAT COMES OF THE MAIN RELAY? GROUND THRU ECU (THE TRIGGER)

power comes from the main relay, to the injectors, then to the resistor, then the ecu grounds them
