Thanks to Mike and Thomas I will be adding another ground to my
"daisy-chained" gauges.

This can be eliminated by using bulb sockets with a separate ground spade
and hook up a separate ground wire.

The problem is that the gauges ground reference changes when the lights are
on and the ground wire has to carry the current for the lights.
