The common point ground for stuff mounted on the
instrument panel generally needs a LOT of places
to attach ground wires. Further, these are seldom
larger wires than 20AWG. This is why the D-Sub
ground connector was proposed.

This technique is much more compact than the
forest-of-tabs product . . . and is best located
on the panel - centrally located to the majority
of devices requiring ground attachments.
You can fabricate your own ground connector
using techniques illustrated here

This example was produced to offer a means by
which lots of instrument lights could be connected
to a single dimmer. Obviously, if used only as
a single point ground, you don't need two-circuits
on the connector. Solder TWO 12AWG grounds to the
row of pins and terminate each 12AWG on it's own
tab at the forest-of-tabs block on the firewall.
