1) Do you not know which pins on the ECU do what?
2) Or DO you know what ECU pin does what, but don't know which O2 wire goes where?


For #1 I can get the answer for you.
For #2 you need to get more info. Is the O2 aftermarket or OEM? What colors are the wires? OEM wires I can help you with. Aftermaket you need find out what brand and then maybe somebody can get more info for you. For instance, Bosch has a different color code than OEM. They come with directions for what wire goes where.
