I am putting together a similar combo but I am running a Motec M48 with the 950 commander manifold and the idle control is done much differently. We actually welded up the triangular looking hole on top of the throttle body and then welded a bung on the side of the throttle body where the current IAC goes. Instead we use a Ford IAC that will mount on the firewall. I was told the IAC/Motec setup is a little older from the design perspective (since the Motec M48 was originally built in '94) but works great. I can try to get you a picture if you like.
