    What do you mean you wish? That adapter is what you would need to do what you are talking about doing. Just without cutting off the ECU plugs.

    What are you talking about? The link I posted is an adapter that converts the OBD0 plugs to OBD1 plugs with the correct wiring changes so all you have to do is plug in your OBD1 ECU.

    I'm pretty sure the B20b doesn't drop in either, but I thought I'd let him figure that out on his own lol :)

    It's still OBD0 I'm pretty sure it will work. Just call Rywire and tell them what you are planning to do and see what they can do for you.
