ground , power : you have to find it, they are every where, depend on where you put your gauge. (best place is to start at the fuse box) I would buy a voltmeter to check.
O2 sensor has 4 wires (at your main catalic converter, under the car, should be 4 O2 sensors there, any of time will do), 2 are for heating, there other 2 are signals, you have to get under the car to see which one is right, use a shape needle to probe the wire, O2 signal should flutuate between 0-1V (O2 signal is on the car ECU connector also, but you have to know the pin diagram for your car)
ask your local dealership which pin are the main O2 sensor signal.
