Ryan ......

what you have is a standard NST....   the larger Beehive structures are
the hi voltage output insulators ( having one threaded post each , there
is normally one on each side of the case, you will also find another
insulator ( smaller ) with 2 threaded posts in it, this is the low
voltage input. The singular post ( normally not insulated) is the case
ground.  If the NST you have is rated for 120 V input, connect the 2
wires from the 120 volt sorce to the double posted insulator, AND
connect the ground wire to the case ground terminal. 

the 2 insulators ( normally on opposite sides of the case) are the hi
voltage outputs... BE Careful they BITE HARD and can kill if not

I suggest you should spend more time reading some of the many web sites
concerning Tesla coils before you attempt to build a coil 

Patience is an important virtue to have in this hobby.........   :) 

take care be careful
