Reply to "Replacement Belt for MTH Dispatching Board"

Ok, I bit the bullet and bought an off the shelf belt. I managed to drill enough of a hole that I can get the pin in place. More on that in a separate post later. 

My question has to do with the wiring. I managed to break off one of the wires that goes to the stud panel. The outside has 3 posts: the top 2 are for the switch, and the side 2 are for power. But on the backside, there are 4 wires. 2 are black. One goes to a disc capacitor and then ties to the frame. To which stud does the other end go?

Thanks in advance for your help!
