Sorry for not quite understanding your question.
Main fuses on the order of 250 Amps tend to have some sort of screw lug either stud and nut or lug and set screw.
Fuse boxes usually have a single screw lug for +ve input and can have screw terminals or quick connect flat connectors for wires connected to the individual fuses.
On the new relay it has the two fuses that connect to the relay and house wiring. The two wires to the relay are already connected. I have to figure out what type of connector to put on my wires so that the fuse can make its connection.
