Just need a quick answer. I'm installing an A/F ratio gauge and need to know which color wire is the signal wire without starting the car. There are four wires, it the signal wire the violet one? Thanks a hoot!

No, the violet is the heater for the )2, the red is power and the black is ground. Leave only one left.

.....okay. Well there arent any red or black wires ![Cry](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_cry.gif)
There is one violet, one beige(off white), and two light brown ones. This couldn't be more difficult![EEK !!](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_eek2.gif)
Anyone know for sure which one it is?

Well I guess GM ran out of good wire so the used light brown for the ground and power wires ![The Jester](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_jest.gif)
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![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)

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?
