MS3X IAC Wiring Question

MS3X IAC Wiring Question
HI All,
Hunting gremlins in my reworked wiring harness and I think I may have found an issue with the IAC that could be causing issues with my idle. The Factory Wiring diagram shows 2 wires coming off the IAC back to the ECU harness (pins 2P and 2Q). I've got one wire (pin 2Q) running to pin 9 on the MS3X plug but not sure where to take the second wire. The MS3 plug wiring diagram shows that second wire on a PWN setup should run to a 12v source but the MS3X wiring diagram just shows one wire for 'Idle". Can anyone shed light on what to do with this second line and if should run to a 12v source or a different pin on the MS3/X...
Thanks,
