I have an Enthoo Luxe Tempered Glass case with a new MPG Z390 Gaming Pro Carbon Mother board. I want to buy the Phanteks RGB Adapter, but am totally confused as to where or what I plug that cable in to make my exterior led case light strips work. I know the rubber coated end goes to my RGB header on my mother board, but where do the other end or ends go or plug into? Also do I new 1 or 2 of these adapters? Sorry if it sounds dumb but I'm totally confused about that.

Thanks for the help in advance.
