HELP me wire my gibson 500t (1 humbucker - 1 vol only)

this diagram doesn't make any sense;

where r the green and bare going exactly into some
magic slot on a vol pot that doesn't exist wtf?

and i have no ground wire from my bridge?

and the 3rd pin on the vol pot appears to be bent back and soldered to
the pot wtf?
 
Dood. The bare and green (in your case bare and black) are soldered to the ground point on the bottom of the pot (directly to the body of the pot). If you dont have a ground wire from the bridge, do one. Solder a wire to the bridge and another end to the ground. And the 3rd pin needs to be soldered to the ground aswell.
