I ran 2 awg using the blue seas 7622 ACR. Mine actually failed and blue seas sent me a new one no questions asked. I really like the remote switch. I used it often to manually disconnect the batteries and to combine them for winching. Another thing I found super useful where the Blue seas battery terminal fuses. Mine have 150amp fuses.
Looks nice. I would be a little concerned that you're not using the larger auto negative posts and only counting on the auxiliary posts which I believe are for lower current draws, particularly on a starter or winch operation.
@Funner I was worried about this too. i did a bit of research and found that those posts are meant to run an electric trolling motor continuously. So should be good enough for a short winch pull. My actual winch is wired to the start battery on the auto terminals
While this is a very true statement it is good practice to ensure the end without the hook is connected to the non powered side of the circuit. Reason being when you disconnect the hook it wont short agaist any metalwork as you swing the fuse away.

Okay, I am not an electrical engineer by any means, when I saw the black terminal protectors on both batteries I assumed they were not in use. I try to pick up hints from people that know more than I do (not hard to find) and pass that info along as appropriate. Glad you're all squared away.
Edit: Looking at specs online for amp draw of 40-60 lb thrust (pretty big) trolling motor 40-60 amps vs warn 9k winch pulling just 6,000 lbs is 332 amps, I would say you have a problem. Stuck in mud pulling an 80 series at 9000 lbs limit is 478 amps. Probably going to melt that terminal.
To me, fuses are awesome. They don't degrade, develop faults or fail closed. Breakers cost more, have more and different failure modes, but are more convenient to use. If you use breakers, the Bussman waterproof breakers are about as good as it gets. and they are great. But if you want ultimate failsafe, fuses are it.
Either is better than nothing, which is what most people do.
Just remember, 12 volts shorted, can burn down your truck, so plan your install accordingly.
