After a few accessories you get a cluster of wires running from your battery terminals. Anyone want to share their bus bar/distribution block set up? I’d like to clean things up.
I'm thinking the only circuit that can't be run through a fuse block is the winch power. Everything else including my light bar should be able to be moved to the new fuse panel. I've got a 6-way fuse panel so a 8 or 10 gauge wire running to the panel should be adequate.Not sure what machine you have. No room under the passenger on a trail. I'm guessing you have a 1000 like Sand-n-Sea. That gauge wire is plenty, even if running up under the dash. You might have an issue with the terminals though and the connector to the stud with wire that large.
BlueSea has an ampacity chart. You will need to consider your total available amps and add up everything you might run at once. Then calculate the total feet of wire from battery to block and back to battery. The chart will tell you what gauge wire you need. I always like to go one step larger to be on the safe side. I also put an inline 30A fuse between my battery and relay, but you might have an issue doing that with such large gauge of wire.
