To connect your PD4045 to your battery you'll bring a heavy gauge red wire (I used 8GA) from your battery (or switch) to the PD4045 "BATT +" terminal. Then you'll bring a heavy gauge black wire (once again I used 8GA) from your ground bus bar to the PD4045 "BATT -" terminal. All of your 12V accessories & lights then get their negative wires tied to the ground bar.
I had a "charging while towing" connection on my last trailer, although it was through a separate connection. The hot wire from your 7-pin connector gets tied to the camper battery with 8GA wire (minimum) and an in-line fuse. There are fancy ways to have it automatically disconnect when your tow vehicle shuts off, but that's a whole other can of worms. Search "charging while towing" on here and you should find the info.
Here's my particular PD4045 setup...

Zach,
That drawing you posted is about 1,000 times more useful than the entire PD4045 instruction manual. Thank you so more for drawing that up. I have been lurking here for over a year, but just had to get around to actually typing something to say thank you.
So thanks.

Can someone please post some pictures of their PD4045 actually installed? I'd like to see where you put it and have the shore power inlet, etc. Most people seem to put this in their galley cabinets somewhere? Thanks so much.
