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.
