upgrading dell studio 15 1555 keyboard to backlit

ok thanks just asked the question before buying a keyboard  :emotion-2:

The connector will be there - you simply need the backlit keyboard.

hi i have the above laptop with a normal keyboard if i want to upgrade to a new backlit one are all the right connections there so it would just be plug in and thats it abd will work ok  or would the right connections not be on the motherboard ?, thnaks for any help
