We're on the same wavelength to this point. - the difficulty seems to be
that the 6 signal wires in the mutlicore lead are very fine copper spiral
wound along what appears to be a soft plastic core which melts when the
copper outer spiral is heated. Very flexible, but almost impossible to
'tin'
before making the join. I think this multicore is some kind of P.O. spec
cable and someone has suggested it's designed for srimp connecting, not
soldering. I can't see how I could crimp up such fine wires into tiny
pins
on the plug. Brain surgery would be easier! Maybe easier to replace the
whole curly lead with less flexible plain copper wire multi?

I assume from the above that each wire comprises a centre plastic core
with copper in a spiral around it then an outer sheath.
Sounds a right pain!
If it was solder before then you can do it again! If it was crimped
then best option is a new lead.
If above not possible then cut out the inner plastic before twisting
and tinning. Problem is strands are probably relatively springy and
will not like being twisted. Best bet is strip 6-10mm before twisting
then cut back after tinning. Are you sure inner plastic is just
plastic and not a core with the copper as a screen?

That sounds sensible. I'll have to get the illuminated bench magnifier fired
up and disect the multicore properly with a sharp scalpel to determine if
the cu spiral is the conductor or a screen.

The whole of the above is academic if you do not know which pin is
which!!!!!!

May have a lead on the pin-out from Sandy Morton below....

The very best of luck.
