Personally with two ends of different cables...
and an unknown joint..
I would want to open circuit both ends..
insulation resistance test across all combinations..
then continuity test with a known Resistance long lead..
e.g. a reel of 4mm earth...
then connector block onto each core in turn..
check continuity to verify if the joint appears to have similar resistive values on each leg..
Just another side point..
if you have two different ends and an unknown joint location..
how do you know there isn't a third cable also branched off the joint???
