I have a 94 vx hatch and im getting a b18c5 swap next week and trying to figure out all this wiring stuff before i get. Im pretty sure ill need an obd adapter for the itr ecu to work,but all this adding 4 o2 wires is confusing me. Could someone send me a diagram or website that shows it exactly and any other wires il have to add?Just trying to get it all layed before I start. If anyone has any pointers before I start my swap please feel free to share. Thanks clay
