Re: ASAP: Which Wire is the Signal Wire for the Oxy Sensors? No, the violet is the heater for the )2, the red is power and the black is ground. Leave only one left.

Re: ASAP: Which Wire is the Signal Wire for the Oxy Sensors? .....okay. Well there arent any red or black wires 
There is one violet, one beige(off white), and two light brown ones. This couldn't be more difficult
Anyone know for sure which one it is?

Re: ASAP: Which Wire is the Signal Wire for the Oxy Sensors? Well I guess GM ran out of good wire so the used light brown for the ground and power wires 
From the sensor to the connector those are th colors, but after the connector, the colors are right; red, black, off white, and violet. I spliced into the off white wire hoping this is the signal wire

Re: ASAP: Which Wire is the Signal Wire for the Oxy Sensors? Anyone know?!?!?!
I think I might of gotten it wrong. When the sender is disconnected from the A/F ratio, there is one green dot at the fully clockwise position, when i hook up the sensor, the Green light goes away and I can just barely see a red light at the fully lean position, after 10 seconds or so it dissapears and the gauge is blank.
Does this sound like I got the wrong wire?
