Whats the fuse box on the positive cable is for on 1991 Toyota Camry & part #?

There is a fuse box that contains 3 fuses directly connected to the positive terminal. I don't know what its called or a part number for it. Or if this fuse box is even needed

Well,why do you want to replace it? If you don't think it's needed,then pull the fuses out of it one at a time and see if anything don't work anymore. They are there for a reason. There are 2 different engines for that car,do you know which one is in your Camry?

I just know its a 4 cylinder. And I am replacing the cables and terminals because whoever had it prior to us obviously didn't know what they were doing and the connections to the battery are bad... however they also bridged the alternator fuse with a piece of metal instead of replacing the fuse. Which is why I'm looking to replace this part. If I can find out what it is exactly and what the part # is

ok,take a picture of it,go to local scrap yard(s) and remove one from a wrecked car. That's all I've got,sorry. I have a 98 Camry 2.2L,but mine don't have that.
