No the two black wires on the o2 sensor are not ground wires. They control the heater element of the o2 Sensor. Be very careful what you do with them because you could easily set your car on fire since the current that runs through them is very high.

I thought the car ran on a 12 volt system? well yes you may be right but for shits and giggles i tried them out both different ways and amazingly they both arent grounds, the car runs finne one way and the other way the car runs like crap thank you very much guys.

The white wire is 02 volts 0-1v
The blue o2 ground

The black wires are for the heater circuit. One is hot and the other is ground. Since it is really just a toaster wire it does not matter which one goes where so long as black goes to black.

No the O2 signal is on the white wire.
