If you have a four-conductor pickup (5 wires - red, black, green, white, bare), you solder the black wire to the lug of the volume pot, the green and bare wires to the case of the volume pot, and you solder the red and white wires together and tape them off. That's for standard humbucker wiring with no coil split, phase reversal etc.
If you have a single-conductor pickup (cloth covered central wire with braided metal sheath), you solder the central wire to the lug of the volume pot and you solder the outer metal braiding to the case of the volume pot.
If the guitar has no metal base plate in the control cavity (i.e. the pots are mounted direct to the wood) you need grounding wires connecting all the pot cases together, plus the neck volume pot grounded to the wire that comes into the cavity from the bridge. If the guitar has the pots mounted on the metal plate, then the inter-pot grounding wires are not needed and you just ground the neck volume to the wire that comes from the bridge.
Sorry, I don't have a photo, but there must be some out there. Have you tried searching on the Les Paul Forum?
