I can remove that block from the board. What's left are four pins sticking out that are soldered to the board. The pins go through the holes on the bottom, and the screws on top are what lock down on the wires pushed into the side (top is what you see looking at it, the side is perpendicular to that, but you get it...).

That's as well as I can describe it. I would have taken another picture but things were working again so I didn't want to mess with it.
