Um....the 92 engine is gonna be OBD1 I think...the electronics are completely different than the 88-91. Do you have ECU from the 92 as well?? was the ghetto wiring done with the intention of being used with the 92 engine?
Your best bet may be a question in the 92-95 forum since that is the expertise you are seeking. they know more about the 92 engine than most of us. or get a Helm's manual for a 92 Civic
Good Luck
