ok i got a 2000 civic ex. for some reason the guy that ownd the car b4 me put a d15b in it. well it has a cel on right now. he told me that the cel was for o2 sensors. well i got around to check em and he was right. i think the codes was for primary and secondary o2s. and also vtec... so i checkd the oil and it was a quart and half over full. so i changed the oil last night and cleard the ecu. so now i only have one cel; and thats for the primary o2. so i guess w the right amount of oil the vtec code was cleared.
so now i looked at the o2 problem.... and there is not plugs for either one of the o2 sensors. in the whole enigne harness... is that the stock jdm harness?? the swap looks good and all stock. so i dunno if i need to find a ex harness or just add the wires to the harness....
please a lil help! thanks

 

are you sure they're just not in the wrong place?

 

ive looked everywhere. im lost! the wires r no where to be found

 

look into buying a new harness, thats some bullshit if it didn't "come with" o2 sensor wire plugs.

 

yeh i know. thats what i was thinkin. does the d15b have o2s in japan?? ne one know?
