I have a new Shurflow 4048 that will be replacing the 5900-0201 that was installed by the factory. The problem I have is that the 5900 has a B+ and ground wire and the 4048 has two B+ connections. I am not sure exactly how the second positive wire that is on the front of the pump is supposed to be wired into the system. I did a pump change out on one of my previous trailers where there were the two positive wires but for the life of me cannot recall how I did that. Any direction would be appreciated. The manual is silent on this wire.
