Hi I bought aautometer air fuel gauge and want to know what color the signal wire is that go's to the oxygen sensor from the pcm. It says to splice in before you get to the 02 sensor wiring connector. Thanks Thecar is a 95 cobra would be the same as a GT tho I would think.</P>

have you tried calling autometer and asking them they are real helpful in getting what they sell hooked up right.

Left O2 is Red/Black</P>


Right O2 is Gray/Light Blue</P>


When I hooked up my A/F gauge (95 GT) I hooked it the O2 sensor itself that way if I messed up it'd just be the sensor and not the factory wiring needing to be fixed. I also used a toggle switch to flip between each bank to see if both were running the same.</P>

Well on mine I didn't want to mess with finding a "hot" wire when ignition is on so I put an on/off switch from the cigarette lighter to the switch whichrunsthe left/right banks. The left/right switch I have is a double pole/double throw (had one laying around). You would only need a double throw/single pole. (Two position toggle switch: power to the middle screw and the left O2 sensor wire on one end and the right O2 wire on the other). I put the toggles at the bottom of the driver's knee bolster up out of sight but still easy to access. Hope that helps.
