Imagine 2 sets of 6 wires. How would I find how many possible connections there are?
Every wire must be used to be considered a connection.

I am not sure what you meant by the sets of wires, but assuming you have two stacks of six pieces of wires, like:
Then A can be connected to 6 pieces (G,H,I,J,K,L), B to 5 (G,H,I,J,K,L except for one) and so on, so the answer could be 6!=720.
