o2 on the cat on a 94? I haven't worked on an integra, but I've got wiring diagrams out the ass. Now first off, I was under the assumption that because your OBD1 you only have 1 o2 and it's before the catalytic converter.... so I'm already wondering why you have one in the cat to begin with, then maybe I can find the appropriate diagram for ya. I also don't understand how you cant match up the wires from the car to the o2. There's only like 4 wires, and they're actually colored with polarity in mind (meaning I bet with some educated guesses, you could figure out which wire went where).
