Are you talkin about the mod that gives the pump a constant 12v? If so the constant is from the battery. The switched is from the power wire on the stock fuel pump harness.

I ran power off the existing fuel pump with a relay which had its own poer from the battery. That way, when the car comes on and the existing fuel pump comes on the accell pump comes on at the same time which its own power source so it doesn't drain any power from the existing fuel pump.

You're talking about the 2 wires to the pump itself right? Because I tested both wires with my multi-meter & neither one had any power when the key was turned. I did hear the factory pump kick in though. I'm confused as to why I didn't see any power through either of the wires.

Maybe your meter is wrong. Check a chiltons book for which one the power wire is. A relay is just a switch that will allow power to your second device after the first device sees power.
