Hi AlexL,

1. The leftmost tab of the volume pot is to be grounded to the back of the pot. Some bend the tab, but I join them with a very short wire.

2. The bridge wire needs to be grounded to the bridge - With a tremolo, I think they can be joined to the spring screws (But I have not completed a kit with this style tremolo!!) Hopefully some one else will add to this.

3. Yes - but than can sometimes be difficult. Twist them together first and then solder to the pot.

Plus, I cannot see the jack plug connections in the picture. The ground needs to go sleeve(?!) connection tab of the plug, and the hot goes to the tip connection tab.

I hope this helps.
