Hi Ferrix97,

I'm not sure why I've never noticed this thread but I have an upgraded 5120 non-backlit to backlit upgrade and a working cable.  Is there some way I can help?  Maybe a picture or some continuity testing?   I had some pictures up here once with the cable and card.  I'll see if I can find them.

Found the thread but the pictures are gone unfortunately.  Is there a way to get them back?
