Just bought the covans dash insert with the autometer ultralite gauges. I want to hook up a shift light and mount it in the dash probably in the center unused area. Question is, what shift light should I get and how does it hook up? I have seen some will pills and others that have a dial on the back to dial in the desired rpms. Does this hook directly to the tach? or does it go to the distributer itself? If it goes to the distributer how do you hook it up with the existing tach wire already plugged in? Do you splice it in? If it hooks to the gauge how does it do so? Any help would be appreciated.
