Help wiring the mini-pac

[j1345]

I have a general idea how to hook up the mini-pac but can't find much info on how to hook it up from start to finish.

Questions:

1) In the tutorials i've seen the buttons have 3 connectors.  Mine only have 2 gold plated ones.  Does it matter which one goes to mini pac and which one goes to the ground wires?

2) As I wire the joytick up to the ground black wires included with the minipac it's almost too short to connect from the joystick to the first button.  Do I skip one of the black ground connectors and just connect the next one in line? 

3) The last connector on the black ground wires where does that connect to?  Does it go back to the mini pac or does it go somewhere else? 
thanks in advance

1. It does not matter
2. Yes it is fine to just skip that connection on the ground wire daisy chain.
3. It doesn't go anywhere.  If you have extra contacts at the end of the ground wire daisy chain, just zip-tie them up securely so that none of those extra contacts will touch any other non-ground contacts.
