Ok I have searched everwhere and I can't seem to find the answer. Which colored wires are for the o2 sensor on the pcm. And when tapping into these i just splice before it plugs in correct? a/f guage install. I have a 2000 gt. What should the guage be doing at idle and driving? I did the black with red stripe but I don't think its right. The guage is dancing all over the place when I'm driving. Thanks

 

you got the right wire. the needle will never stop. at wot it pegs the rich side but other then that is all over the place. not sure on the 2000 but on my 92 there are 3 wires. two white are power and the black is the sending wire, the one you tap onto for the gauge

 

Ok so this guage dances all over the place while Im driving. When is it actually reading anything? Is It? I mean If i hooked it to the right wire ( red black stripe). Im also having a nightmare with the fuel pressure guage. I know how to install this but the F---ing company sent me the wrong adapter for the schrader valve. Does anyone know for sure which one it is? I'm pretty sure its the 3276 from autometer. Any help would be great.

 

Ok got the adapter problem fixed. About this guage.. whats the story. anyone?
