i guess i need to get the thing in my hands and see it before i start asking more questions... just lookin to understand how this 12 v system all works.

Only two wires from your 7 pin plug will have anything to do with your RV 12 volt. The rest are for trailer external tail and marker
lights and get power from the tow vehicle when going down the road.
Those two wires from plug going to your RV interior
lights, I don't think even hook up to the converter, they would hook to the
battery to charge it going down the road.
Two wires from battery into trailer are all that gets hooked in from the tongue. Probably to converter connection marked battery.
Camper stuff such as inside 12 volt
lights,
furnace blower, water pump draw power from battery on tongue. That "normally" is just 2 wires. Black and White as I recall. You have some extra stuff under the sink, can't comment on that but basically what you are trying to do is...
AC Power shore power to converter
Camper stuff --- pos & neg --- converter ---- battery on tongue
two wires from 7 pin to charge battery from 7 pin
Other wires from 7 pin to trailer marker and
tail lights (rainbow of wires).
I kind of stink at explaining this but that converter sits between battery and all the inside camper stuff. Auto switches between drawing from battery on tongue or using AC "converted" to 12 volt.
The rest of the wires are for turn signals and such and are a separate system.
This diagram might help explain the 7 pin wires, which then continue into the camper.
