The Workshop Manual shows all five instruments with ground wires. Generally
I think you will find that if a grounding tag has one wire it will go to a
component, if it has three or more it will go to the body. Tags with two
wires could be either, but glancing at the diag for a 71 it seems that the
only ones behind the dash with two wires are the ones that daisy-chain to
the gauges. There only seem to be three body grounding points - one at the
front for the lights and starter relay with two wires, one behind the dash
with five wires, and one in the boot/trunk with three wires.
