depends on what OBD series you are running on. OBD2 P72 will need wire relocation. better if you bought a adapter. OBD2 P71 will just wire up. you will need to do a 4 wire O2 conversion, VTEC Switch and Soleniod, and IAB (Pissed Off------> you are wrong about IAB, it;s Intake Air Bypass.) Butterflies is just a terminology for it.
