Not speaking specifically about the TR6 but rather Triumphs in general,
the instrument cluster has several ground wires that provide a good
ground path for all the instrument backlighting as well as selected
idiot lamps.
So all you have to do is examine the arrangement and make sure that all
the gauges and lamps are connected to a good ground source and
everything works. Usually, the clamping studs that secure the gauges to
the bezel are where the ground wires are attached.

Subject: TR-6 Wiring Question
I was reinstalling my rebuilt (not successfully) speedo this weekend and
found a ground wire that I have no idea where it goes to! I know there
is one ground wire that gets put onto the speedo (top post on mine),
this doesn't seem to be it. (I installed that one) It comes out of the
same bundle of wires that go into the ignition module. It has the round
spade on the end. I hooked it into the bottom post on the Speedo, but I
had to really move the harness around to do it. Anyone have any clues?
The wiring diagram was no help.
