I see the WF8735 is a smart-mode technolog converter/charger unit but alot of folks have problems like I did getting the WFCO products to go into their charger modes.
I would at least go to the next series up being the WF8900 series so that you could direct replace the converter/charger unit with a PD4600 or PD9200 series unit if you have problems getting your WF8700 series to go into smart mode charging. It appears to be a self contained unit where the WF8900 series has the converter/charger module separate from the power distribution center.
Your other questions will hard for anyone to answer other than a previous STARCRAFT owner of your same unit. Maybe someone will dime in with your answers.
You should be able to trace down the shore power cable and how it connects up and make some decisions from that. Should be pretty straight forward on 120VAC wiring. My 30AMP shore power cable goes directly to the converter/charger chassis where the 30AMP circuit breaker is installed. I have no idea what you are referring too with those other switches you referred to... Also note that the POPUP PORTAL link also has manuals available for the older POPUPS - might find some good info in those. My starcraft 2008 manual has an electrical wiring schematic in it. If your model doesnt have the electrical diagram in it perhaps you can look a couple of years newer with the same model and maybe find a diagram.
