The braided wires are the ground connections (pickups and output wires) so go to the back of the pots (pickups) and to the sleeve connection (jack socket). On the jack socket, the sleeve connection is the one at the top, that is pressed to the metal barrel that runs through the jack socket and which touches the 'sleeve' part of the jack.

'Mono' jacks are better described as TS jacks (tip + sleeve) whilst 'Stereo' jacks are better described as TRS jacks (tip + ring + sleeve).

The spare wire on the back of the pot is the bridge ground wire.
