Hi guys i always get mixed up the wiring looms when it cames to year,type,Vtec,ECU.... so i got 3 Hondas a 98 civic EJ9 D14 90BHP what i believe to be OBD1 and then i get mix with my CRXs one is a 94 vti vtec B16A2 engine using a P30 ecu and the other a 97 ESI vtec D16Y8 engine ( i haven't checked the ECU yet) and i have no idea what wiring looms are on them i cant find a OBD2 port on them so are they OBD1 or am i just wrong all together??
