    where is the blue switch in the electrical layout?

    The blue switch is optional for turning on and off the bluetooth. You could wire it between the bluetooth module and the 5 volt power. But that's only possible if you have a separate bluetooth module. If you have the bluetooth build into your amplifier, you won't need the blue switch. I have a separate bluetooth module, but I haven't wired the blue switch up because it isn't really necessary. So it's just for looks in my case haha.

    You will have to buy a female xt60 connector. You will have to wire this according to the schematic shown in the steps. You will then plug your battery in the female xt60 connector, and you will have power!

    Do you have to use the power board or can it be wired right to the switch?

    You will only need the power distribution board, if you have a 5V Bluetooth receiver. Otherwise you can also wire al the 12V's im parallel, and you don't need the power distribution board. The distribution board does clean up the wires do, so I would recommend it either way.
