Each junction box has a specific number of connections. The connections are universal, they can connect to a load cell or to another junction box. The idea is to create a daisy chain of junction boxes. One connection leading to the next junction box and one connection leading to the previous junction box. Remaining connections can be used for load cells or for connecting to other junction boxes. The junction box at the end of a chain would only need a single connection leading to the previous junction box with the remaining connections dedicated to load cells. In the end all the chains must be combined into a single cable which leads into the central receiver. You will require cables for connecting each load cell to a junction box and cables for connecting the junction boxes to each other and to the central receiver.
