Common dash cluster issues question

The heavy wires on the amp gauge have always had ring terminals, real hex nuts, and internal toothed washers. All of the wires to gauges can be attached the same way. Dark blue to fuel, purple to temp', gray to oil. It aint so easy to bypass those pins for indicator lamps.
How I attach a addon ground wire... phillips head screw at lower center of center pod gets approx' 4 inches of wire with ring terminal. Then a male spade terminal other end. A length of wire with female spade terminal goes from there to behind the left kick panel. More or less mirror image the factories ground wire behind right kick panel. The spade terminals allow me to unplug my ground wire if necessary.
If/when I lower the column and pull the panel out a bit to trouble shoot in the car, I didn't loose my ground when I lowered the column.
