Our '81 westie has no kitchen light nor light over the bed, though
there there's some wiring in the shelf/tray/channel (what is it really
called) over the sink.  The wire that looks like it should be live
comes into the shelf through a hole in the headliner above the poptop,
but it doesn't have any voltage on it.

I have not been able to remove the headliner;  we took out all the
screws, but the headliner is held in by more -- perhaps the channels
it runs in are glued to the bodywork?

So I tried to poke a wire inside the headliner from the interior light
above the driver's door to above the tray.  Seem to have hit metal in
the middle.

Where might it be possible to run power (12v) from, to go to the
shelf/tray/channel?

thanks yet again
Alan
