    You can still run your OBD2 ECU but its more complicated. Its much easier to just install an OBD1 ECU and be done with it. OBD1 engines don't use a rear O2 and OBD2 ECUs look for it.

    96-00 is OBD2 and 92-95 is OBD1. If your Civic is all original then it should be OBD2. Either way you can have an OBD2 car and swap in an OBD2 engine or use OBD1 engine.

    I don't think your friend knows what he's talking about. If the motor in your car is original, never been swapped or messed with, then it's OBD2. 96+ uses OBD2.

    Check what ECU you are running. That will help us give you an answer.

    As I said before, all 96+ Hondas use OBD2. If your motor is stock and hasn't been swapped out (which, judging from the pictures, I would guess that it is) then your car is OBD2. Even if the motor has been swapped out or rebuilt or whatever, I don't see why the wiring would have been changed. People usually only switch to OBD1 when doing an engine swap because it's easier to tune. Your friend doesn't know what the hell he's talking about...

    If you still don't believe me though, then jack up your car and put it on stands, and check to see how many o2 sensors you've got. There should be 2, one in the header or header downpipe and one in the cat converter.

    That means someone messed up with the car before you bought it.
