your wiring skills have to be pretty good if your going to do this. if anyone is interested, i will text mesage or email you my diagram. im not posting it on here because i doubt anyone really cares as much about keeping the fuel pump screaming as i do.

i just figured i'd support John at Power-io because he was so nice and actually gave me an extra free pwm relay.
here is the diagram i was referring to, i got a few messages about this. i have confirmed that the pump does slow down when the ECU tells the fuel pump controller to. It is alot of work and alot of soldering but the pwm of the pump is preserved and the relay is capable of a whopping 75amps.
