Can't take credit for any of it. Got the majority of the dual battery install parts from this gentleman's video. He has listed them in the information tab for the video. Very detailed and great tool for anyone installing dual battery. I believe there are 100's of threads about this process with all sorts of ways to do it on the Honda SxS forums. I know, because I read most of them before trying it. This video however explains it the best.
Thanks for the grease and fitting tips, definitely going to extend the vent lines. Found some great ideas for that on the forums. The snorkel however I'm still debating, is it really necessary for thrashing in 1-3 feet of water? Most I've seen come up through the passenger side cup holder which I'm not the biggest fan of getting rid of my passenger's beer can holder permanently, lol, but seriously.
To me, the snorkel is another one of those good insurance mods. I play in the water a bit, I don't go scuba diving with it but ya never know when someone else rode by in a lifted buggy with 35s and made a rut you can't see under water 🤷♂️ .
Snorkel, and vent lines for gas tank and diffs. I ran mine just behind the bench seat above air filter, never had water in there again
Here is the front light bar that I purchased:
