I have a 1995 Civic Coupe with a 1996 ITR Swap and using a JDM P73 ECU with harness.
Do I get one for OBDI or OBDII?

I thinking either 95 GSR or a 97 Type-R?

I did a search and someone recommended a OBDI such as a 95 GSR because the JDM P73 is OBDII but still runs as OBDI, it this right?

Any help or advice is greatly appeciated.
