O2 sensor replacement: Which wires are which?
I have a 00 Si and I need to replace the O2 sensor on my cat, I bought the sensor below which came with the directions:
White = Power (12v)
White = Power (12v)
Black = O2 Signal
Grey = Ground
On my car's O2 sensor harness, which wires are which for splicing this into?
White = Power (12v)

your car / your new o2 sensor
green / white
green / white
white / blk
blk (or other color) / grey
This is for the main one. If your changing the 2nd o2 its the same thing except different colors. But white is always signal.
