Help... Temp./Fuel Gauge

It's almost like you guys have done this before....

So I got lucky, after some fiddling around. The gauge works!

However, it isn't accurate, now it will go up to somewhere around 140-160 when hot. It's barely between the markings on the gauge.

When you shut it off, and start it up again, it will bounce to the middle where it more should be, and then take about 10-15 seconds to slowly drift back down to inaccurate reading.
