ECM PINOUT IAC HI/LO

Hey everyone!

I am nearing completion of my wiring of the Holley HP. I am trying to figure out which side of the IAC is Lo and which side is HI. All 4 wires go to the PCM on the wiring diagram so no help there.
I can tell there is continuity between blu/red & yellow as well as wht/blu & brown. i am not sure which is Hi and which is Lo though.
I cannot seem to find a K8 pinout that would help me resolve this. Can anyone point me in the right direction?
 
Any takers? A Pin our would be really helpful. I cannot seem to find one for the K8. I can trace the wiring colors through the diagram to the stock ECU and harness to determine the pins if the pin out calls out IAC hi and Lo accordingly.
 
I have come across this one but do not see the indication of IAC circuit.

I decided to just install the IAC to the Holley HP and command the IAC steps to make sure it is wired correctly. I just cannot seem to confirm my suspicions.
