Color of O2 Sensor Signal Wire

Hi, I want to hook up a Air/Fuel gauge ( Narrow Band ) and want to get it right the first time, What is the color of the signal wire on the O2 Sensor ?
I did search the forum but couldn't find anyone that did a 2009 with a 4.0, I do know that I should connect to the sensor closest to the engine on the drivers side, some of the other posts said the wire color was black and some said red ? But these were different years then mine.

Thanks in advance for any help on this.

I don't have the 2009 schematics yet but there's a very good chance that 2009 is the same as 2007 and 2008:

PS violet/green
DS white/blue

You can use either one for a narrow band A/F gauge.

Another idea.... I use a scan guage with all four readings set to a single 02 and I set the rate to high.

Yeah it's a bit of a compromise and not as cool looking.. but it works fine even when shooting nitrous. Then when your not interested in WOT a/f.. you have MANY other capabilities.
