Unless I'm mistaken, the "00 b16a2 harness" is out of the 99-00 civic which is one piece from the engine to the ECU, you should be plug and play for the O2, but getting the ECU in there is going to require a OBD2b-to-OBD1 harness.
unless that was a miss type. Then you'd need to know which teg or which OBD1 civic harness you have.
if you're using your CX harness then you'd have to run the heater wires (two black on the O2)
One to the ECU (A6) and the other to the yellow/black wires at the driver's shock tower.

Re: (Relic1)
ECU is plug and play aswell, the car side harness is OBD1, so no conversion was necessary. I know the engine side harness is OBD2 and it is plug an play for the 02 sensor, but at the shock tower where new engine harness meets 93 car side harness, wont match up....that is the question.........

you'd have to know where the engine harness drops off the O2 heater control line.
If the harness is OBD2 and there are plugs at the shock towers, it has to be an integra harness.
the heater control should run through at C103 pin 2, you'll have to add one wire from there to the ECU at pin A6
