12v ring terminators,wire routing,outlet

[Blacktank]

what i have,
50 feet each size 10 and 12 wire
blue sea 12 circuit fuse box
a pair of basic crimpers
and no money to speak of till next year sometime but dont want to waste what i have on crap


would these ring terminators be good enough?

routing of wires
batteries behind passenger seat,fuse box close to them
so passenger's side electrical is easy,just run the wires
drivers side i have a slot cut in the floor to run wires for water pump,light,tv,fan,maybe a car stereo

what i am thinking is run the wire to water pump and light and then something like these with the appropriate size wire to it

as an outlet for the others

the other me thinking option would be to just run two large wires across to another blue sea fuse box


so what do folks that actually know what they are talking about think? the run would be about 7 feet to the pump and about 9 feet to where i would put a distribution
