use the diagram with the red rectangle around it
for this application
use only an OEM Honda 02 sensor , do not use an aftermarket universal

there is a reason
the shielding on the thimble is incorrect on the aftermarket 02 sensors so the exhaust pulse from #3 cylinder causes a spike , so the 02 sensor appears to cycle every 720 degrees of engine rotation
the system will never be in fuel control
it will be difficult or impossible for a DIY type to track that down and solve it so
use only an Honda OEM 02 sensor purchased by the vin of the car for this application .

do not ask me how i learned this .
pain is a very good teacher .

should you require the waveforms to verify , just ask
