Many ways to do it.
Depends on the boat layout.
The links are just examples.
Both my boats have a inline 8 ga maxi fuse at battery with a switch feeding a fuse panel.
I feed the livescope and graph with 10 ga from the fuse panel.

The 2 conductor connections can be anything from a Tmotor plug to insulated spade connections.

Really depends on what you have to work with as far as space and access.
In both boats I have a fuse panel mid ship fed by 8 ga from a fused /switched connection at the battery.
You may have to run separate leads which just adds more fuse/switches.
Just make sure you fuse the run from the battery, at the battery and again at the leads to the equipment.
Good luck with the project
The links work but show robot check.
Not sure why.
