I am having trouble figuring out how to connect the two bare wires to the AC of my powerpack.  I have EZ Commander Set up.  I have the green wire attached to the supplied switch, and the red terminal attached to the switch.  From what I am reading, I am suppose to attach the bear wires to the AC terminals of my powerpack.  But I really don't see AC terminals on the EZ commander.  Any suggestions on what I need to do from here. I just don't see that anywhere to hook these wires up too.

Ok, well Im new to this hobby and to be quite honest, I really don't know where to begin.  I think, just from doing some research, the HO scale would be best.  I am like everyone, working on a budget, I see online and on this website, train sets, and just locomotives.  Some of the "locomotives are very pricey"  More than the train sets, in some cases.  I guess what I am looking to do is have a maybe an oval, or an oval with some sort of incline.  Maybe if I get really into it and not too frustrated, two tracks.  But where do I begin?  What train would some of you guys recommend?    Ireally don't know too much about wiring, but I guess that would come with some time and reading instructions ( I assuming for more complicated structures)
