Might sound silly, but are you absolutely sure?
I mean VW's have the permanent and switched live exchanged in the ISO
plug, that's an old porblem with them (so much for ISO). But each one
I saw had them.
Maybe a previous owner had not known that situation and, to get rid of
the unwanted switched one, has cut it off and sealed the blank end?
AFAIK the radios anyway take the power from the permanent live. The
switched live is just that: A sign that you want the radio to operate

Then I may make a suggestion as you have aleady the car in pieces :-)
You've found a switched wire, so you might as well slap a relay (radio
shack?) behind the radio, route a cable from the permanent live to the
relay IN, route a cable from the switched live from the ignition to
the relay SWITCH and route a cable from the relay OUT to the proper
ISO connector position. Place a fuse in the feed from the permanent
live and you're done.
Crude, but it should work just fine. The relay will seperate the
circuits, and using the permanent live as the power source and using
the switched life from ignition just to switch the relay will make
sure you'r not overloading the switched live.
JM2C (make sure the fuse is dimensioned adequately)
something in my mind. I had perm live at the usual switched live
position, and nothing where the perm live should be (factory).
I've cut the wires on the Kenwood side (I'm not cutting the factory
wires) so that the perm lives goes to the required perm live, found a
suitable switched wire I'm happy with, thought I've got to have full
ignition on, put that to the correct place. All is good.
Ta for the input, I'm normally happy with wiring but, normally I'm also
used to at least dealing with one thats been screwed with a bit, so you
don't mind screwing it up a bit along the way, but this car hasn't, and
I'm trying my damndest to at least keeping it looking that way ,
sometimes you just need a bit of secondary input.
 So any other changes are reversable too
That will explain why I couldn't find switchable in my mk2 golf then ;)
The permanent live was in the wrong place but switched was still
missing, no wire to the ISO connector at all. But as covered in the rest
of thread, found something I was happy with (though not key in ignition
stage) and connected up to it.
There were no funny smells or smoke this morning on the way to work so
so far, so good. Tomorrow the cam belts... 
 Parts 'should' be at the dealers now, booked into garage for that
