About a year and a half ago i completed the auto to manual swap on my 2000 civic. Since then i have had to get smogged and of course i couldnt because the check engine light was on (rewired the auto ecu to work) ... BUT ..yesterday i bought a manual p2p ecu and tried installing it to get rid of the check engine light but the last jumper harness did not fit into the last slot of the manual ecu. So im wondering if I just bought a bad ecu or if they are all that way? Basically im asking if the auto and manual ecus should be different?? thanks in advance guys!!

 

cmon guys ... my smog deadline is today! lol

 

You probably bought a OBD2a ECU while you needed a OBD2b

 

do you know if the p2p-a12 ecu is obd2a or obd2b?

 

btw i still have the auto engine harness if that makes any difference

 

These are all for manual transmission

2000 Ex is 37820-P2P-A12

1999 Ex is 37820-P2P-A11

1998 Ex is 37820-P2P-A34

1996/1997 Ex is 37820-P2P-A33

 

the one i bought is a 37820 p2p - a12 ... hmmm .. it seems like its the right one ... would it have anything to do with the fact that my engine harness is still a auto harness? .. thanks a lot man

hmmmmm nnooo ooonnneeee has an answer to this question?

 

you will not use one plug because that is the auto part. (i think this is right only one i have done was on a cvt tranny car)
