Ok cool, I was just wondering since I have a plug to connect to to the O2 that has about 6 or so feet of wire on it already as well as it's shielded (the signal wires need to be shielded to keep out interference).

ok so i matched up the wires to my book and one of them say to plug into the vtec spot on d14. and two of the other wires says to plug in where some other sensors are. i think im just gonna leave the p72 ecu in and fixed the revving up and down at idle. im worried that it might screw up something if i wire it up wrong. and i dont have the money to fix anything.

The ECU pinouts on the P07 are different than other Honda ECUs.
That PDF I linked you to is right out of the Factory Service Manual so the wiring is correct in it.

Here is the picture from the back of the book:
L1H1 Pinout you'll want to use the "Except California" side.

thats a better picture. Ok im not disagreeing with you but its saying the white wire goes to d14 witch is where the vtec wire is. do i run them together that just dont make sense. so tell me this the way i learned to read the pins is left to right on top and left to right on bottom being 1-11 is on top and 12-22 is on bottom. i've done alot of ecu re-wire jobs like dpfi to mpfi, and lots of vtec jobs, and a few other things. but never a o2 hook-up. so i just want to get this right.

This is a good picture of how to read the pinout on the ECU.
