    I just bought a d15b for my eg because of the price and more power then my dx d15b7 but i dont know a whole lot about these d-series yet, i didnt do the swap yet but i started wiring an si harness on the motor and i noticed it didnt come with an o2 sensor or vtec oil pressure switch (i knew it wouldnt but thats a different story). so am i going to have to do any wiring for the o2 sensor or can i just get a new one and what model engine do i get it for?

    ok well if you have the d15b thats has both to use the p08 ecu you will need a 1 wire o2 sensor . to use a 4 wire you will need a p28 ecu
