https://drive.google.com/open?id=0ByS5BI… I looking for this part to repair my Alienware 15.
I have attached a link to the service manual for the Alienware 15 model. On page 28, the cable you circled in black in your photo appears to be labeled the “Keyboard Backlight Cable”. I can’t find a part number for just the cable, so you may have to replace the entire keyboard to replace that one cable. If you do a search in your browser for “Alienware 15 replacement keyboard”, you will find several options to choose from. Just make sure it is the correct part number before ordering anything. http://topics-cdn.dell.com/pdf/alienware…
