ignition problems

I totally forgot to mention this, and this is more less a question for 67dart273, my ignition is currently wired to a toggle switch, the previous owner told me that the ignition switch was most likely burnt out, and instead of replacing it, he spliced a wire into one of the red wires in the loom that goes to the 5 pin ignition module harness and wired a toggle switch up. Now my truck will not start unless that toggle switch is flipped on, and it will not shut off ether unless the toggle switch is shut off.
So my question is, should i have the blue wire coming from my voltage reulator spliced into the same wire that the toggle switch is wired to? this would be a 12v ignition source so i dont see why it wouldnt work, and i was also told i could have it wired to the ecu power wire as well and it would be ok. the way it was explained to me and as i understand it the voltge regulator needs a 12v ignition source and it really doesnt matter where it gets the 12v ignition source, as long as its switched ignition source. I'm a little baffled with the way this guy has this truck wired, the wire that the toggle switch is getting power from is not the ecu power wire, but another red wire that runs to that 5 pin module connector.
