chris: As has been mentioned. Two wires were attached to that electrical socket. They were fed down and either out the back through the wall mount or clear to the bottom of the pedastal mount and out. Then connected to a convenient 110-120ac power source via a plug-in connector or hard wired and most always switch conrolled.
The wires on yours having been previously removed for who knows whatever reason. Being it frayed from old age, broken or burned etc. For SAFETY PURPOSES foremost, also a quality restoration and as you already have everything you need including the basic light mount fixture and necessary mounting socket fixture plate. It might be a real good idea, to possibly rewire it all.
This would simply entail removing the light socket by unscrewing same. Then a quick trip to your local electrical outlet for a very common and cheap, new plate mounted light socket. Plus possibly if necessitated, a length of their recommended wire and any little incidentals desired.
No big deal! Nothing else required, special parts purchases needed or shipping expenses involved, but worth far more than the minimal investment required.
