OBD2 --->OBD1 IACV wiring question

[BlackGoat]

I have done a OBD2 F23A swap into a 91 Accord. It is done works great except at idle it bounces up to 1500 rpm+ and back down constantly. The one thing I had problems with, was the wiring for the IACV. The old engine (OBD1) had a 2 wire connector, and the new engine (OBD2) has a 3 wire. What is the proper way to connect this up? I assume this is my problem, but if there is something I am not thinking of that could be the problem please share your thoughts.

Oh that harness lol. i hadn't read the other posts until i repied with the first one. sorry about that. the harness i used was for the f22a, wired obd2 inj. plugs to it,using 94/95 accord ecu. tried using an adapter plate for the obd1 iac it didn't work right though.i just plugged the wires into it how they originally were. what did u mean plug the 2 power wires together with a pin??? as far as the diagrams go i just used the repair manuals to get them.
