okay I away from my main computer right now so I can't edit pics right now but I'll do my best to describe them to you.
ok you should see two contacts for each direction on the dpad I will tell which on you need to solder to.
1. for up you solder to the left contact
2. for right you solder to the bottom contact
3. for down you solder to the right contact
4. for left you solder to the upper contact
5. and for the ground you should see a square with an another square in it below the screen ribbon cable you solder to there
and that should be it
