I'm trying to figure out the o.e.m. type gauges. Three connection on each, power, out to the sending unit, and negative for return to zero. Where does the return to zero connection connect to? Is it a temporary ground source? and if so, where and how? Does a relay provide a ground switched off of a starting circuit?
