Here is another photo I have found of the way I set mine up.
It is in the R&D phase all connected up to the pizza box template.
You can see that I have flipped the box over to fit the wires better and for a cleaner install between R&D and finished product...
The box was used when I got it and came with some short wires.
The black terminal strips were salvaged from some old residential furnaces as that is what I used to do for a living.
They made the wiring much nicer to deal with.
