Wiring without enough coffee to get us wired

The water heater is mechanically installed, so we've gone back to electrical work.

This is a short entry, since pulling wire isn't particularly exciting. I may revisit the topic if something challenging shows up.
Me being unexcited:

I created a spreadsheet of what needs to be wired to what. I use that as a reference when pulling the lines.

 I've run most of the upper DC power and control lines from where the fuse/distribution box will be:

To where they'll end up at various switches, gauges, sensors and self-destruct timers. There will be a control panel on the john's outer wall, near the fridge. I've also run the lines back to the items that get switched or sensed (like the battery & solar monitors and controllers, water heater, H2O pump, water & LPG levels {the white/red pair going into the floor behind the LPG valves}, etc.).

Finally ran the line to the LPG level sensor and hooked it up. Clearly, I need to stress relief this end to the wire feed-though.

Next step is to mount the house heater and and cut its combustion vent holes.
