So yep the other side usually I would not show this side but there is wires going from the green board to the red one.
So the green solid colored wire is ground which most of the time green is ground but not always. And the red solid colored wire is 5V that powers the green board.
Boards came from Open Pinball Project that I backed on Kickstarter. But is the Ikea of pinball board making as everything came in component parts and have to know how to solder and read directions. :)
Well, for low voltage DC, especially battery powered items, the normal convention is Red is Positive, Black is Negative. But there's no real hard rules about it.
The 'Green is Ground' convention is for AC wiring, when you have the current carrying Hot and Neutral lines, and the non-current-carrying Protective Ground, With that setup, Ground MUST be either Green, or Green with a Yellow Stripe. And no other wires are allowed to be Green or Green w/Yellow.
Nobody expects prototyped low-voltage DC gear to follow the conventions, but the closer the conventions are followed, the easier it is to troubleshoot years down the road when you're trying to remember how you put everything together.

Ah yeah I could have tested the 5V line if it is positive or negative but I just wanted to signify it as power. And it bugged me that the illustration for the green wire was a black one.
I facepalmed as I always do grounds as green unless it is the ground braid for a pinball machine that is actually a silver braid rated at 8A which pretty much gets hooked onto all the metal spots and up into the head as well for the older pins.
And eventually I am going to make my own boards but for now I am using these Open Pinball Project components. :)
