Bob in Mb, I will be putting in a converter. And, I will use it for the internal lighting. I can't imagine that there is any point at which the 7-pin is tied into this system, except maybe the 12V charging wire? I'd have to take another look at my notes which are currently at home. Please, correct me if I am wrong.

Yes, your charging wire from the 7 pin will have to go to the battery/converter as well as a bonding wire from the TV's ground in that bundle to your ground buss/battery (-) side. As mentioned, bad grounds are the things that generate problems. ALSO: Use quality crimp-on terminals and splices for you wiring and get a pressure crimper (not the pliers kind) for crimping. Cheapo wire terminals are well know for becoming loose terminals, sometimes within weeks of installation.

And wire nuts and Scotch-Locs, fergetit.....

You have not mentioned whether you will have a battery in the camper.
We do not have a battery in the camper we use the vehicle battery if we need to use 12V and have a small solar charger if we kill the battery or are staying for a while. We have LED lights and that is all the power we use if at a non-electrical site , so power consumption is very limited.
In any case all your interior wiring will begin at the converter.
Your tail lights , turn signals , running lights , brake lights , and brake controler will run directly from the source.
As mentioned before white is ground and black is hot on interior wiring.
Turn signal etc. color code will vary depending on manufacturer but white should be always ground.
Do not use 12V for your fridge when camping , only when travelling , it is a battery killer.
You converter should have simple instructions that are easy to follow.
