Ive spent the majority of the day wiring an air fuel ratio gauge and i cant seem to find the O2 sending wire. it changes colors after it passes the connector a few inches behind the sensor itself too red-green, red-grey, grey-black, and red. i cant find any connection in the engine bay with these colors. closest i can see, that i think it could be is a white connector here. it seems to be coming out of the harness from down by the sensors.


the colors on it are white-black, red-green, purple-green, and tan-yellow. this just doesnt seem right. does anyone know where and what color the o2 sending wire is in the engine bay? it would be greatly appreciated.

EDIT: Well i was able to determine what the wires are as they come out the back of the sensor and black is the sending wire however as soon as it hits the connector a few inches back teh colors all change. now how do i find it.

stock o2? the air fuel gauge wont work for crap on a narrow band sensor. all it will do is make a pretty light show, if you really want to know the a/f get an Innovate LC-1 and use the gauge with that
