P72 is for a GS-R, but the OBD1 versions can be reprogrammed to run H22s. To the OP check out http://technet.ff-squad.com compare your ECU plugs to those Katman has listed.

Re: (94EG8)

3 grey plugs, 3grey holes = obd1.

3 grey plugs + 4 holes = obd2 a or b depending.

Tell me the three letters after "P72" and I'll tell you exactly what model it came out (any US ECU).

37820-P72-003 should be a JDM ECU. As I mentioned, I can only look up USDM (and a couple other countries too actually).
