Holley HP users

FYI - I'm working with an old friend from Detroit who is still with Holley. I had a conversation with one of his IT techs and will share the response from his team on this issue.
So, is there a solution for the two wire IAC on the BBK with 4 wire Holley harness? I am in the same situation. Please advise on adapter or how to wire so ECU will work. Appreciate any help!
