You are going to have extra stuff left over you useing and obd0 harness with obd1 motor

 

Idle air has a black and a blue/yel wire, IAT has a red wire (can't recall the trace color) and a green (can't recall the trace color) wire...even though I can't recall the traces, its the only one like it. If you have another two pin with a black wire and an orange..that your fast idle control..it'll hang if your manifold doesn't have it.
