The sketch shows what I am adding this year in E1.31. Can someone let me know if this setup is correct? The other question I have is: Looking at the picture of the Ray WU PS, it looks there are 9 slots. I assume one for incoming and 8 for outgoing. Is it possible to add additional wires to the same slot? Based on the calcs, I can run all of these lights on one PS. Does the P12 board send 12V from each universe? Does the power for the lights leaving board get powered by the Power supply or incoming. The instructions for the P12 appear to show through the PS. If it helps, the different colors are separate universes, the bold line between the strings are power injection points, and the line colors are the typical setup.
