Insatlled FAST - what to do with factory O2 wire?

[Warp6]

I just finished the installation. I was looking around and noticed the factory O2 is still in place and is plugged into the factory harness. Do I remove the O2 and plug the factory O2 bung and just leave the factory harness with nothing plugged in?

Really doesnt matter.I would remove it and get an 02 plug for the header

Okay, thanks. I didn't know if the open factory O2 lead would cause any problems
