o2 sensor wires, which wire sends the signal?
i am hooking up a narrowband air fuel gauge and need to know which wire to tap into, 4 wires, i know 2 are heater wires, 1 is a ground and one sends the actual signal, wires are black, tan, brown and purple, i belive it's the purple wire but not sure so if anyone can confirm this..thanks

i am awful at reading diagrams but i think it's the purple wire that gives the signal, if anyone knows for sure let me know.. and the instrucyions say purple is the most common on a 4 wire o2 sensor so that leads me to belive it's purple. thanks for posting the diagram byron
