The controller has a nice little press jack setup. You cannot plug the typical connector into it since it is meant for bare (press the top of the jack, stick wire in, release). Most of the strips I have gotten had a plug on one end, and bare wires on the other. There are also tons of adapters out there, or DIY is pretty easy.
As for power, the controller uses those jacks also. Not a barrel plug. It is pretty simple, the pictures on Amazon really show it all.
You also might be surprised on the size. I thought they would be much larger.
