I have the wb O2 sensor screwed into to the sensor bung and the harness coming up through the tunnel just at the console location. I'm attempting to pick apart directions that were written in chinese and translated to english. The O2 sensor and gauge are a cheap import set.
New message from me to original seller:
About a year ago, I purchased an AFR gauge from you. The installation instructions aren't very clear. There is a little wiring connector that has different colors than the O2 sensor wires which are back, gray, white and little pigtail has red, yellow, white and black. If I can't hook it up properly, then it is useless. Can you help me?

hi dear friend
O2 sensor instructions
The white line is at heater ab
Black line signal line C, gray line signal ground D
The green wire of the instrument is connected with the black wire of the sensor. The gray line is connected to the negative pole of the battery.
One white wire connect with the car shell or battery negative pole.
Another white wire connect to the ACC line of ignition switch
The white line is the heater and does not distinguish between positive and negative electrodes
About the air fuel gauge, please see the installation instructions.
ME: Your previous message
There are no green wires at all having to do with the gauge or O2 sensor. I have attempted to pic apart the AFR gauge connections from the universal directions. I have a yellow wire up top that could be what the green wire is supposed to be. It would be nice if there were directions just for this gauge and O2 sensor on one piece of paper where it would all make sense.
Have you personally used this gauge and O2 sensor combo? Thanks for the help!

Well, the directions are still not clear. Below is a picture of the O2 sensor pin out and a picture of the gauge with a yellow wire up top. This may be "signal in". The lower pigtail on the gauge has 4 wires. Red power+ Black power- White ign+ Yellow illumination+.
