battery wiring review?

[Diemjoe]

I am finishing up the last of the electrical. I am putting the battery in the Tongue Box and am wondering if I have the wiring for it understood correctly.
Using 7 PIN cable to connect to the tow vehicle.
Do I run a black power cable back to the battery? (No factory installed tow package)
Adding an on/off switch and fuse between Tow Vehicle and Battery
Running the positive power from Tow vehicle to Battery, by-passing the trailer frame junction box
Connecting the Solar Pos and neg wires from Solar controller to battery
connecting pos and neg cables from battery to the trailer frame junction box.

Seems simple, too simple?

Thanks. I have the PD4045 in the galley and it is fused. My assumption was that would be enough. Let me know if wisdom dicttates additional fuses.

Thanks for the additional info. I am wiring it up this weekend and will take it into account.
