Thinkpad E531 backlit keyboard

[tpd]

Hello,

I would like to replace non-becklit keyboard with illuminated one on my Thinkpad E531 laptop. The problem is that there is no clear information (videos, at least photos of it working etc) related with subject. A seller from ebay told me that this is illuminated keyboard - "because it has backlit cable":

As I could see, non-backlit keyboard has two cables as well. Can anybody confirm that there is such a keyboard, to share some photos/link at ebay where I could order it?

Thanks!
