Im looking for ECU pinouts for 22644 AA020 made by Hitachi ,it came out of 97 legacy EJ18 OBD1 , I have searched all over the net and cant find it.

what I managed to find out the hard way  is that the early US legacy had and ECU that looks the same (only difference is yellow connectors) but the pinouts are not correct.

I found out that ECU 22644 AA521 ,22644 AA010 , they look the same with green connectors and I think they might be correct?
