so im swapping a b18b1 from an obd2 integra, into my obd1 95 civic dx.
i went here, http://technet.ff-squad.com/hybrid.92-95.obd2.htm
i pretty much have a clearer insight on everything i would need for my swap.. but i was also reading online and supposably obd2 cars have two o2 sensors?? obd1 cars have one?? im using the obd2 harness for the swap and the obd1 ecu to power it, what will i have to do for the o2 sensor situation? would it be something with the header, like a header swap from an obd1 integra or would it be a wiring harness situation?? (btw, im nottt really that experienced i just read alot on this stuff, so this question may be obvious to some. please excuse my ignorance)

You only need to run one O2 sensor. The obd1 ecu will not look for the other bank/sensor. Is there a reason as to why your are going to run the OBD2 harness?

I agree with the post above. Since you're replacing with a B18b, you could reuse your current harness.

well the integra i have is a parts car, and its obd2. to save money, i was just going to use as much as i could from teh integra as possible. the link i posted the guy was explaining that it could work correctly, just some plugs wont plug up. but how would i use my dx harness with no problems what exactly do i do?

The real Ryan

Just run the front 02 sensor, the one in the manifold not the catalytic converter. That is "Bank 1" and all OBD1 will look for. As far as plugs that won't plug up from the DX harness are the distributor plugs and injector plugs. So you will need to run an OBD1 b-series distributor and OBD1 injectors to use the DX harness. WHat OBD1 ecu are you running? your DX ecu won't work, so I'm assuming you found a pr4 obd1 LS ecu?
