    you only need one O2 sensor for OBD0, do what CAFROG said and plug the other hole.

    I forgot the SIR had 2 O2 sensors, from looking at the ECU pinout list it looks like all OBD0 ECU's have O2 Sensor A @ C16 and O2 Sensor B is only on the SIR ECU @ C8, if you have an SI or HF then you could just run the extra O2 sensor straight into C8. What year and model is your CRX? I assume you're using the harness that came with the car and just wired in the VTEC?

    Oops...sorry. I thought OBD0 was one O2. Is this a JDM B16 OBD0 thing?
    If you know where it goes on the ECU...just run a line, get a spare pin and you should be good to go.

    Here's a few pictures of the pins on an OBD1 plug (pretty sure its the same theory for you)

    Look at the last picture. He's holding a red wire and the pin I speak of is on the end. If you know a donor car or a junk yard...hit it up and get a few of these off the harness at the ECU. Just cut the wires as long as you can and use the link below to see how you can take them out. Solder or use a tube connector (if you are good at making a solid connection) to run a piece of 16 or 18 gauge wire throw the firewall and to the O2 where you can connect it there with either a salvage clip that connects or jsut use solder or tube connector again. Super simple. Pin goes into the clip pretty easy too.

    Not sure about where C3 and C8 are on OBD0 clips but sure its somewhere. here's one I found

    And here's the pictures for the pins at the ECU (look at the last one and zoom in)

    obd0 pr3 b16 set ups require the 2 o2's as you stated. one sensor per bank.
