Okay. I was thinking about maybe building the adapter in the thread and connect some LEDs. That should work right?

Oh wait I get it. The ground pin is a pin set for input right?
About connecting pins to themselves..what if I oops and connect two set output pins to each other? That doesn't sound too good.
Guess I should check the ribbon cable between the boards first as a warm up. Just a resistance check for each pin or something.
