Hi, folks first post I have made so hope this works!
Car: 00 civic ej9 1.4 sport.
Engine: Jdm sir2 b16A N/A
Wiring & ecu: complete rywire d to b series EWH with subharness! Obd1 P30 UKDM spec prob same as USDM!

My problem is on ob2b there is only 2 ports on charcoal canister, I believe obd1 civics/integra had three one that ran to some sort of solonoid and then to map and into IM? Pls correct me if wrong! My first problem is I cud do with some sort of diagram on how this should work, parts I require to do job? My probs is emissions I am trying to just get as close to standard setup as possible! Also if I need to get solenoid I know my loom has no spare plugs to power it, so what would or should I do folks?

do you have a visual emissions inspection where you are? If so (and they know the layout or have diagrams like RonJ posted) you are going to fail as the obd1 evap system you will need to setup to work with the ecu you have will not match obd2 specs...

Thanks for diagrams Ron much appreciated! Vlu3s- no visual inspection so should not have to worry about that, I have just rebuilt complete engine, to realise only little less Smokey so was wondering if this evap really was my issue, the engine idles and power is good, but u can tell it's over fueling from smell from pcv pipe! They diagrams are full of info about evap systems, but I just don't understand what I need to get to make it as good as possible! My friend is my tester but he can't get me away with to high emissions but a bit over am sure will be fine!
