I have this ecu with the numbers

37820-P13-A12

on the tag. It has OBD2 connectors; however, I thought that the p13 was an OBD1 ECU? IS this possibly an F22a1 OBD2 or an H22a1 OBD2? Does it matter?

The guy I bought it from thinks it's from either a 95 or a 96 Prelude.

The reason I ask about the F22A1 is from this site:

There was one year where there were OBD2 P13s...in the 1996 VTECs.

 

So that means this is from a 96 H22A1? Could this possibly be from an F22?

 

slhondaparts gives the '96 F22 Prelude a P12. And it gives the '96 VTEC the "37820-P13-A12".

 

yup, thats one of those rare *** odb2 p13s...a real hot item for people swapping an h22 into late 4 gen accords/ acura cls

 

Awesome, thanks guys. I actually bought this to resell it, so it's on ebay right now. This was actually one of the questions someone asked me, so I appreciate the quick response.
