OK, I bought an auto meter air/fuel guage. I got everything wired up and it seems I run lean all the time so I'm guessing that I wired up the sensor wire wrong. does anyone know which wire I'm susposed to connect it to? the book I bought never really explained which color of wire to hook it up to so I sorda gave it the old college try. right now I have it hooked up to the grey wire with a red stripe. also, does it need to be wire right at the O2 sensor or can I hook it up in the engine bay wire the wire is easy to get. right now I have it connected to the engine bay. thanks guys.
