I have an existing standard light switch that controls a single outlet. I would like to replace the switch with a dimmer switch. The dimmer instruction expects two black wires and two white wires (and a ground) in the box, but there is only a single white and a single black (and a ground). The white wire and black wire come from the same larger white wire, where the first layer of sleeve has been removed to show the two of them. How do I wire this up correctly? **Instructions** [![enter image description here][1]][1] **Wall Box** [![enter image description here][2]][2] **Dimmer Switch** [![enter image description here][3]][3] [1]: https://i.sstatic.net/BXeYS.jpg [2]: https://i.sstatic.net/Abnkw.jpg [3]: https://i.sstatic.net/E0iED.jpg
