    I have on my hands a JDM B18C OBD2 ECU with the pigtail plugs. I looked to find a secondary o2 sensor wire on the A connector but found it missing. Is it that OBD2 in japanese cars have only 1 o2 sensor? Before telling me that it's OBD1 I found the revision number on a website and it stated that it was JDM OBD2. I'm trying to install this OBD2 JDM motor in my OBD2 GSR but with no 2nd o2 sensor I dunno what to do. I'm thinking of just getting a USDM OBD2 ECU.. what you guys think

    jdm itr/ctr motors obd2 only have a primary 02.

    if you're going to use the jdm ecu, you simply don't need the secondary after the cat o2. plug the hole, or stick an o2 in it to plug the whole, but theres nothing to wire.

    your state emissions may require this though, so be advised about that,.
