alright, is there anything else i need to do for an obd2b ecu to work on an obd2a harness? Just throw the jumper harness on and im set right?
(searched)

edit**yeah i know i need to wire up knock sensor

Well.....I did this myself (99 civic, running of a 96 prelude ecu) All you need to do is buy the extra plug that you dont have. If your car is 96-98 OBD2A you have the "D" plug(smallest one), but you need the B plug (second plug) And if your car is 99-2000 obd2B (or 2001 for a prelude/integra) then you need the D plug and not the B plug

Then you need to buy a shop manual, and go to town on the re-wire (its not hard just time consuming)

I looked but I cant seem to find pics of the ecu plugs...but you get the idea.

How about a little info on the swap? etc...

oh yeah i know about all the ecu plugs and even have it memorized on what they look like.
I was just looking for confirmation that I just need to run an adaptor harness or re-pin my obd2a wiring harness for an obd2b ecu, for everything to work...Im having a bit of paranoia right now about it...lack of confidence in what I think is right

edit**whoops...99 b18c into 97 civic ex
