      FITech fuel pump circuit ??

      Does anyone know how this circuits works ?? Is it simply a key on circuit or does the ECM use something like a tach signal to trigger power to this lead?? Was looking to make sure if the engine stopped power was cut to the fuel pump. Or do I need to add an external switch to cut power to the pump if the motor dies or, and I hope it never happens, I'm in a wreck.

      Finally got a reply from FITech. The ECM controls the fuel pump. You get a 1.5 second burst at key on. Then as long as there is an RPM signal the fuel pump is energized. So no need for any extra fuel pump control switch
