o2 sensor heater after the cats

does any body know if the heater on the o2 is turned on by ground or positive. and does the heater circuit use a relay to turn them on.

curious which codes and how did you get the original code to go away... and the wiring for the O2 sensors are generic, you can google for the wire color coding.
