I also have a TS and the fuse panel/converter is right above our utilities compartment. Out of the back of the fuse panel there are extra wires for the empty circuits. You can run a wire down thru the floor into the top of the utilities compartment to your new Sani-Con and then install the appropriate fuse in the panel. That is exactly how I did my water pump power when I upgraded my water pump, the stock wiring was not large enough. So my new circuit feeds the pump relay controlled by the stock wiring and switches.
To wire it to the panel you have to pull the panel out. Please be safe and make sure generator will not auto start, shore power unplugged, and disconnect the house batteries. The extra circuit wires (on mine) were short, black wires with bare ends exposed. All ready to attach a new wire! I used a multimeter to select the right empty fuse spot and match it to the right wire. To get the new wire down below I carefully pushed it down through the floor where all the other wires pass through. Then find it in the overhead of the utilities compartment. To get working room you probably need to remove the two under-wardrobe drawers.
