Mustang air/fuel Purple wire?

[cobrarwanab]

Does any body have a autometer air/fuel gauge (non wideband) hooked up to there 99-04 stang? Where did you connect the purple wire? I have the instructions for the gauge but it is not helping. 4-wire o2
Here is a link of what i am talking about. See if you can figeur it out.
