[DeTomaso] Electrical Gremlins

[clay willmott]

I would think the lights not affecting the temp gauge is good and there was a bad ground?  

On my early 71 there was one screw holding a 90 degree tab into the back of the gauge thats where the 0.25 inch push on tab went.  This particular brass screw did not hold the gauge together only the 90 degree angle metal to the back of the gauge.  Did you check the other backs on the other gauges also?
Ho doe the tab attach to the back of the temp gauge on your car?

The temp needle still moves back and forth from time to time.  I doesn't appear that the gauges are now affected when I turn the parking lights on,  not what I expected.  How could that be?  I guess it's possible that I still don't have a good ground,  but I would be surprised if that's the case.  There were two nuts on the back of the gauge that I tightened,  but the nuts only appeared to be keeping the gauge together,  not keeping the terminals in place.  It seems that I have three possible steps to take,  run the new ground wire to the stud,  check the connection at the sending unit,  and make up a new ground cable from the trans to the chassis.  Any other thoughts?
