PRO-FLO ignition switch wiring

[Bobbystill]

I am trying to figure out where to wire in the switched 12v line for my edelbrock pro-flo ecu. The directions say Connect the Pink/Black IGN switched wire on the main harness to a +12 Volt switched power source that provides +12 Volts when the key is both “ON” and “CRANKING”. Can anyone help me keep it simple stupid and post a picture or description of where I should connect this wire? I'm trying to learn my vehicle's electrical system but half of it is from a TBI monte and the other half is from a carbed V6 el camino and I don't know what's what.

I tapped the same wire used to kick the fuel pump relay for mine.

Actually I wired it to a fastronix bus bar and used it for all kind of other stuff that needed switched power

Thanks! This is probably another dumb question, is the stock fuel pump relay powered by the stock ECU or is it through the ignition circuit? I'm trying to figure out what I can get rid of from the old ECU.

on my k10, the ECU was completely removed and i still got the 12v signal to the fuel pump relay. i think the only thing that will cut it out is the oil pressure switch (atleast on my truck)

Thanks a bunch that's a huge help!
