I have no idea which resistor to use, but you could just get an o2 sensor and olug it in... Right?
I've heard, repeat, heard that you can just attach it to another sensor. It doesn't make much sense but I just heard that...

I had the catalytic converter changed on my 2000 accord about 2-3 years ago and almost immediately the check engine light came on, I pulled the code and it had a P0420 code for a catalytic converter low effeciency. After going back and forth with the exhaust shop a few times, they kept telling me at first that the O2 in the side of the cat must have went bad. I knew better but changed it anyways and kept the reciept. The light came on the same day again and took it back to them where they again checked it out and said I had an exhaust leak from a cracked exhaust manifold and that it was causing cold air on deceleration to be caught up in the exhaust and was throwing the reading of the O2 to a lean condition and causing the light to go on. I finally got tired of their crap and called a friend of mine at Honda and he said it was a cheap cat that would probably last for quite a long time but it just wasn't efficient enought to pass the PCM tolerances and he told me to figure out the thread pitch of the O2 sensor and install a spark plug anti-fouler in the catalytic converter and then screw in the O2 sensor to that. The anti-fouler had to be drilled out a little to accomodate the O2 but after that the light has stayed off ever since and that was about a year ago.

Default did anyone ever get anything

ive had my car for about a month now, i took the cat off and saw someone hollowed it out, and the o2 sensor needs to be replaced, but i know the engine light will come on, does anyone know what Resistor or wire to run too.
