Possible Plug n Play Standalone

So the other day I was bored and got to thinking if we can do OBD-1 conversions and use a P28 computer why couldnt we just leave our motors OBD-0 and run the AEM Standalone EMS for the 88-91 Civic, Integra and CRX and a plug and play or are the plugs different and then even if they are couldnt we just get the adaptor harness. I dont think the harness would be needed though since our cars are already OBD-0.

first, let me say that obd1 is a better option because it is more easily tunable. second, we have a very different "version" of obd1 so it probably wouldnt be as easy as you think
