[HELP] Adding additional fuse box to original battery


So I'm going to add some new things to my F10 such as underglow, starlight, active exhaust etc and I want everything electrical to be done properly to avoid becoming Ghost Rider.

So instead of having to splice wires and twist them together to connect the mods to power, I want to add an additional fuse box to the battery and have everything fused for safety.

Problem is, how do I actually add extension wires to the + and - of the battery? It isn't that simple compared to older cars, just get a terminal splitter and add your wire, the big red attachment on the + seems to have entry points for additional wires, or are those for something else?

If these are indeed entry points for extension wires, what wires/connector do I have to use? Or what do I actually have to do to add another wire for power?

Those empty slots are fused already.

The part to plug into those slots are:
Socket housing 61136925176
Flat connector 61136920094

Get 8 AWG cables to crimp on the connector and run it to your new fuse box.
