The JDM P73s I've seen were the same size as thew USDM P73.
The USDM P73 is an OBD2 plug and OBD2 program.
The JDM ECU is an OBD2 plug, but an OBD1 program.
I had one in my 1992 Civic with a jumnper harness for my B18C5 and it is for sure the same size as a USDM OBD2 ECU and it does indeed run an OBD1 program.
This means no extra o2 sensor, no crank fluctuation sensor, etc., etc.
