Im not exactly sure what you mean. The photos clearly show how the cables are routed at the rear. The first photo shows how the cables are attached to the metal piece. From that piece forward theres only a single cable that is joined to the cable that comes out of the firewall with a connector that looks like this. Its a very simple setup.
As I said earlier, just make sure the drums are off or you might not have enough slack to hook the two ends into this connector because the shoes will hit the drums and not give you enough cable.
