I have and Ibanez two pickup electric guitar for couple years bought new. Discovered that a couple of wires came off and not sure where to solder them back :-(

First is the three way switch the black wire is disconnected, does this get soldered as a ground where the other black wire is soldered?

On the tone pot the Green Wire is twisted to the white wire which is soldered to the terminal but I cannot imagine that it was installed that way just bare twisted no tape. Is the green wire supposed to be soldered to the top of the tone pot? Also the black wire you see is just hanging out, is that also a ground that should be soldered to the top of the tone pot?

Appreciate any help! Just a poor indigent college kid.
