That "N" means your car is a '92, so it should have the same standard OBD-1 plugs as any other, such as those on a '95 GS-R ECU.

I just checked Dan Platt's G2 swap guide to make sure I'm not crazy, and yes, a real 95 GS-R ECU will plug into a real 92 Integra's body wiring. I have no idea how to help you, because something is seriously wrong here.
