4 wire Universal NTK Narrow Band O2 sensor wiring?????'s

[GAMEOVER]

Can someone please school me on the wire color's coming out of a O2 sensor...Umm where do they go? New Sensor has 2 white wires, 1 Black wire, 1 Gray wire....OEM plug coming from harness = 1 Pink, 1 Purple, 1 Tan, 1 Green

OEM
Pink= Ignition
Purple=High Signal
Tan= Low Signal
DK Green= Heater Low Control

black=signal
gray=ground
whites=heater

Sorry, still don't get it...I have 2 Signal wires(hi-Lo) 1 Ignition wire, 1 heater low control...:nixweiss: What would be what?

[Gregs]

ok yeah
signal high=signal sent to pcm
signal low= pcm ground for the signal wire^^

i'm not sure on the heater but i would guess that ignition will be the heater power. i will guess again and say that heater low control is ground also... which makes sense i guess since the signal low was the ground for signal side of things, the heater low would probably be ground too:nixweiss: i would grab a multimeter and check the heater low to see if its a ground
