I've read this several times and still don't get it. It has the plug that goes to the machine. From that plug, you have a wire that goes to the wall and one that goes to the foot or knee controller (2 wires off that plug). Do you want 2 wall cords?
I just don't get the question. (Not that I can give you an answer either way, but I'd like to understand the question.)
