Hi guys , i'm from Bulgaria and from http://hondabg.com , at this moment i'm doing a swap in my 5 gen eg4(obd1), the new motor is b18c4 , so far so good but i have a bit of a problem finding the pinout's of the ECU(p9k - OBD2 B) so my question is can someone help me :) I'm turning to you cause i see that you help allot of guys around here , and at Honda Fan Club Bulgaria we could not manage to find such diagrams or anything close to the one ...Thanks , Ivaylo

The ecu has obd1 plugs but in all sort's of tablet's and information i found about it the people say it is obd2 :(
 
Yes i know but .... that is the way they give it ... i just found another motor like this , it is Honda Civic with d16y2(OBD2 "A") made after 1996 in UK and it has the same plugs ...tomorrow i will try to figure out if it has something in common with my ecu...
 
maybe this will help (from 1998-1999 Civic Aerodeck Workshop Manual)

this might be easier to read - looks to me like that the pinouts are the same as OBD1

Yes it helped , but there is a new problem the car won't start . Now , we conected everything , checked it 2 times , the ecu sends error 41 - which we didn't connect , fixed it , and again , the car won't start , it came out that the injectors don't inject the fuel .... they don't open . We tried a few things , like getting a "+" and "-" from a different place and they WORK , but when we connect them to the ecu , they stop working :(
 
Can the immobilizer be the problem , cause it is not wired and on the wire on the ecu there is 5v ... ? :(
 
i called the guy that gave me the motor and he gave me the immobilizer(the full set , even the steering wheel) and she still does't start ... :(
 
bump for an interesting problem; i hope someone can get you going!
