Bussmann Fuse/Relay Box Questions

[WODWorldWide]

Hey there Bussmann users or electronics people. I am setting up my wiring for the rigid lights coming in and wondering who is using the Bussmann Relay/Fuse boxes.

I guess my question is what is the difference between the Bussmann 15303-3, 15303-5 and 15303-6? I am looking at purchasing one and they all look about the same to fit 5 relays and 10 fuses.

Here are some examples on the links.
15303-4
15303-6

Looks like the more expensive one has nuts and is assembled and the other one isn't :noidea:

I would buy one from Erik at Wired Wagon LLC. If you are just going to make one and don't have the crimpers it's probably the cheaper way to go. He provides a great quality product that myself and a few guys here can attest to.
