I got a usdm 99 si engine b16a2(obd2-B) and a 96-98 DX hatch (obd2) I do not wish to go obd1 . As for the O2 sensors I'll see once in swap mode. Do I keep the dx wiring and add to or put Si harness in (using p2t ECU)? Vtec wiring and (SI)motor mounts are all that is needed? I read the articles but just wanna make sure. Thanks for the infos and the good stickys.
