I'm gonna snag an electric fuel pump so I can do away with the mechanical pump & regulator setup. Just read too much about those cheapie regulators blowing diaphragms and what not.

My question is, is there a certain wire I can tie in to to power this thing. I don't want to have it on and pumping just when I have the key in the first spot. I have wires going to the plug in the bumper, not sure if I should mess around with tying in to those or if I should run a new wire from somewhere in the engine bay back to the pump.
