I just got done swapping my b16a2 in my 2000 dx hatch.

It's running alll 2000 civic si wireing & ecu.
I used to own a 2000 civic SI and noticed there is a O2 sensor that comes down above the cat. The dx engine has it's O2 sensors on the top of the exaust manifold. So when I put the civic si wireing harness on there is only one place for a os2 sensor (which plugs into the header), but the computer is looking for another one which would plus into the cat. How can I get this senor to shut off or where could I plug it into the wireing harness.


PLease HELP!!
