request: photos of accessory wiring within engine bay for dual battery setups

Greetings,

I'm currently planning to add some light duty accessories to my Tacoma such as a light pod and 12v switched outlet in the bed.

I was hoping to see some photos of dual battery setups people have, specifically where they have the accessory power terminated at within the engine bay.

IT seems pretty common for people to use a cutoff switch and marine grade blade fuse block mounted to a tray ontop of the relay box behind the battery for single battery setups, not sure if this is the same for dual battery setups though?

My goal is to start out with a few accessories running off of my single battery and then install a dual battery kit later on prior to adding on too many more or demanding accessories such as a winch and multiple lightbars without having to relocate or re-run the accessory wiring.
