12v power under R31CB V-berth

[robshepherd87]

I am planning to install a SCAD TM2 tank monitor for our holding tank, but I'm having trouble finding a good source for 12v power. I would like to mount the display on the V-berth pedastal, so I need to get the power somewhere in the storage area under the berth.

I've considered using the supply for the shower sump; is that feasible? Would it be better to run a dedicated line from the buss bar?

Thanks!
