If you use a cable to splitter (which then cables to the lights), make sure this cable is not a cross over type, as that will counter the cross over nature of the splitter to light cords. If you are just plugging the splitter into the receiver, you should be fine.

For clarification since I will have to make the 3 cords up that go into the splitter:
If the plug's release lever is up on all RJ11 plugs in this assembly, and pretend the black wire is to the left on all four wires looking down into the plugs, then this is correct and not a crossover affair? I guess I could put an ohmeter for continuity on each left wire at the plug and see if a crossover hasn't occurred too.
(I think I ran into this crossover affair with some normal phone cords before. ???)
