First thing, I was afraid to get this car but really wanted it when I seen the CTS Gauge not working... I want to get this fixed ASAP, as well as Tach. I might just go buy aftermarket ones tomorrow but just curious if I can get these up and running...

I read possible bad cluster, bad sensors etc... I can't find where the Temp sensor is, read that it's suppose to be between plug 6 & 8? or 4 & 6? somewhere between those haven't had much luck but only fiddled around for a little at it while I was working on it.

Haven't found anything on the Tach though.. Any thoughts?

 

found this post looking for something else. in case you haven't found it yet the coolant temp sensor is drivers side front in between the front two plugs. single green wire.
