      Will both the LCD and the step down wire to the same wire? Will this lower the 12 volts from the lcd?

        You split the 12V output of your power supply. One set of wires (plus and Gnd) goes to your LCD controller board (check polarity!) and one set to your step-down-converter, which is regulated to 5.1V for the Pi.

          My point is that all the power supply’s under 80W only have one set of output wires.

              @MadScientist sorry for so many questions. But won’t I need to solder them in a “T”? Or get a T splice?

                Don’t be afraid to ask…

                You can solder the wires together but that’s not really needed.

                  @MadScientist ok awesome! That really did help I wasn’t thinking of doubling them up in the terminal.

                    This converter isn’t adjustable and it’s only 5.0 v would this work?

                      or

                      should do. They are adjustable via a potentiometer. Iam using the latter one for a Pi Zero but the 3A are enough to power a Pi3 easily. You should check aliexpress.com since most of the low priced parts already come from China. They will be even cheaper and are the very same product.
