Well, if you have a CRX then they have no reason to plug in an OBD II computer unless you make a big stink about them needing to.

All you have to do is pass the sniffer test.... RPM based test.

See you are the only one who's kind of in the bad position... just because you updated your wiring doesn't mean you need to do that test... I mean, if it passes that way it would pass the sniffer anyway.

But again, like mike said, just change the oil pump and then the ECU wont know the difference.

I'm just not so sure why you changed to OBD II if you are still running a D series, not worth it in my opinon but it's your call
