Mounted the eb832 and the wire box yesterday. Looks pretty solid. I am going to be designing and printing mounts for the DOS and the head unit, I have a bit of extra room in the controller section for mounting my return pump controller and heater controller. I have not figured out exactly how I want to route wires for those yet. It is getting awfully hard to keep sensor wires separate from power, but I think I have it all planned out. If not I have a contingency plan that involves a ton more work. In the images below you can see the 4 outlets that are being routed to the backside of the tank. The "top" 4 are servicing the sump.
