With most Fiats, the real light cluster is removable, though
you may have remove trim to get at the mounting nuts, a
pain in the butt.
Don't let the nuts drop into a hollow body section.
Generally a pull off connector, to a PCB
with all the bulb holders riveted on it. The riveted connections
after a few years can become oxidised joints. Also check
and clean any grounding tags under bolts, and the chassis
they bolt on to.
If everything looks clean at the back end, look under the
bonnet, you will probably find some 1/4 blade connector
strips bolted to the metalwork, as electrical grounds, nicely
placed to catch all the road, and winter salt spray. Worth
giving them a clean.
Dry joints hard to fix, most soldering irons can't cope,
overheat the PCB, can sometimes do better with a
soldered wire link from points where the heat isn't
conducted away from the iron so fast.
A thin smear of Vaselene on the PCB edge connector
seems to make the fix last longer, if there is room
retain the connector with a Tywrap or insulating tape,
then it won't work loose.

Would that be in the light unit or elsewhere on the body?

Usually in the light cluster - check for corrosion along the tracks and the
connectivity to the car body.

Thanks for the info.
I presume the earth cable is 'black' as I don't have a wiring diagram.
I was thinking of stripping back a small part of the cable (black) and
grouding to a local earth near the rear light cluster
and making it permanent if all works ok.

Thanks again
The rear light cluster connector
block was tarnished. Cleaned up with some
emery cloth and all works ok.
