OK, I've read the how to but am still unsure about which wires to tap into. I am not the greatest with a volt meter and could use some help.

When I test the 4 wires I find two of them to be 12 volts. One of them is around .2 volts and one is ground.

Is the white wire (.2 volts) the sensor signal?
Can I tap into either 12 volt wire for power?

 

white - signal
red - power
black - ground
pink - heater (do NOT cut this wire)

this was on my car, i'm not responsible for mis-installations

 

Thanks. The wires are different on an 02. I'm figuring the white one is still the signal and either 12 volt will work for power. I hope that's right since I just did it. I'll find out tomorrow when I get the code cleared.

 

My understanding is that:

Black: signal
Grey: ground
White (12v): power
White: heated

But let me do a search to double check. Have ya tried looking in the FSM? Its prob in there somewhere as well.

wiring depends on if your tapping into the o2 sensor wires or the engine harness wires prior to the o2 sensor plug
