i've spent the past hour searching.. and need to get my car done so here goes:
i have a borg warner O2 sensor. the wires are different colors. i have two white instead of two black, i can deal with that.. but i have a black and grey instead of the colors on the stock sensor.. can anyone tell me WHICH (black or grey) goes to the green on the harness?? if i can get that one, then i can guess the rest. thanks.

*edit: '94 GS-R

 

i could SWEAR i've seen a post on this in the past. nobody?

 

i'll give this one last bump. does anyone know which wire on the harness is power? i'm told the two white are heaters.. and the grey is power, black ground?
can anyone tell me what the wires are on the STOCK sensor? i know the two black are heaters.. and guessing the green to be power? i have no clue.
HELP!

 

Sorry, I don't know the answer either... however you may want to break out your multimeter and you can probably figure it out...

 

i just compared the two.. and guessed between black and grey.. ala a bomb squad technician
no check engine light.. runs fine. i'm good to go.
