[Coco] CoCo Keys2USB - Problem

[coco at jechar.ca]

Hi I have a CoCo Keys2USB which I have used in the past however the 
piece
of plastic holds in the keyboard ribbon cable must have fallen out and
when I moved the keyboard and realized that the connection had come 
loose
and I am not sure which is the correct way to plug it in nor do I know 
if
I plug it in the wrong way If I will destroy it can't find the 
documentation I had nor does there seem to be a PDF online can anyone 
help.
