How to identify is ECU is OBD2 or OBD1?

I am Looking to switch to OBD1 and I seem to find both OBD2 P72 and OBD1 P72 ECU's...Can anyone tell me how to confirm the ECU is a OBD1 P72 94-95 Integra GSR ECU without cracking it open? Are there any no's I should be looking for?

Thanks!

just look at the plugs. OBD1 has 3 plugs continuous and OBD2A has 3 plugs with a space between 1 of them.
