Does anyone know which wire is the reference and which is the output on the rear O2 sensors (99 GT)?? I know the 2 whites are not it leaving the one black and one grey wires. I looked in my factory service manual but could not find the color codes for the sensors. I read the thing on ZXracing.com (in the MIL eliminator section) but I heard they labelled the black and grey wrong (should be the opposite of what they labelled). Can anyone confirm this?? Thanks in advance.
