Well, i searched and got 2 conflicting methods. I'm hooking up the stock GTX o2 sensor. it has 1 black (signal) wire and 2 white wires. From the diagram it looked to me like they both went to 12V and it was grounded through the case. I did that and now it runs hella rich. So, now i'm guessing its the other opinion i found and one of the white wires goes to ground. anyone know which?

heated o2 sensors are much more accurate over a wider range of engine conditions... at low speed and idle it is especially helpful. its not pointless but you wont get a "z0mg this car runs so much better!" feeling eitherEscort GTR -- 11.87 @ 117.6 mph -- 320 HP / 325 Ft. Lbs. @ 23 PSI
