I have a 97 hatch with a jdm b16, I used the harness & ecu p2t obd2 that came with it but it wont pass emissions so i bought an si ecu usdm & harness it doesnt have all of the plugs to go in the ecu i did this on my own and I need help!!!!

 

I believe you'll be needing an OBD-2A to OBD-2B conversion harness.

 

will that make up for the missing plug? and make it pass emissions ?

Yeah, I think you want to find a obd2A usdm b16 ecu. Wich I think your best option is a del sol ecu. They are probably pretty hard to find, though.

Another option, might be to get a vafc and lean it out before you take it to get tested.

 

I would get a vafc and do that but here they just plug in there comp to yours and checks for codes!!! thanks !!
