I'm looking at putting an OBD2 H22A from a Prelude into my OBD1 CB7, wondering if someone has any experience with this swap, and exactly what jumper harness I will need to use the Prelude ECU. Any help appreciated, a newbie but very eager to learn. More so, my question is do I need an OBD2b or OBD2a - OBD1 jumper harness.. Thanks in advance. Or would the year of the car that the H22 came from have to do with whether or not it's an OBD2a, or b?
