Rope Light didn't come with plug and I dont know what kind to use or how to put it on.?

Check your packaging, there should of been a connector in with your kit. It will have two pins sticking out of it. That is what is jammed into0 the wires inside the rope light itself. It will have a screw cap that goes over the rope and screws the connector tight, then gets plugged into the cord itself. If you don't find one, a lighting showroom can help or Lowe's and Home Depot should have those connections. The other thing that does not appear on your list is a transformer. Did one come with your kit? If not it will not work, rather it will burn up from the 120V when you plug it into the socket.
