I just ordered my NX nitrous kit and I am in the process of purchasing gauges to go with. I am going with a modified Autometer A/F gauge from www.gadgetseller.com. I need to know if anyone has hooked up a A/F ratio gauge on their 99 or newer cobra. I have heard it is better to hook it up to the the PCM and not right at the O2 sensor. Does anyone know what pin I can find this wire? Diagram maybe? I saw that someone in the Lightining forum had posted pictures from a Tech Manual that told the exact pin location and wire color. Can anyone help?
