Wiring L92 with O2 sensors

[68problemchild]

Newbie here so forgive the basic question.

I purchased EFI live, and a separate LC-1 02 sensor. Putting in the new harness, it also has two plugs for O2 sensors.

I am putting the harness in over the next two weeks from Current performance.

Do I plug the O2 sensors into my new harness or keep it separate? If the harness, I need another sensor, one for each header yes?

thanks so much.
