JDM B18c in a 92 civic cx hatch, i'm using the civics obd1 harness with a jumper to the obd 2 ecu,, v-tecs wired in, there is only one o2 sensor on this motor at the back of the b-pipe, 4 wires 2 black one wite and one green,, juts wondering where they go on the ecu,, the only pin out i can see is A-5 at it says for secondary o2 but where do the rest of the wires go?by the way i'm using a obd2a ecujdm

 

2 black wires i believe are ground , the white is a signal wire that goes to the ecu , and green im not sure

 

thanks,, does any one else know where the green wire goes???

bump no one can help me with this one?

 

the 2 black are ground yes and one is a signal and the other is a heater. it heats up the o2 sensor
