'78 31ft Sovereign Newbie question regarding fuse block.

[GHC]

Hello everyone. Long time lurker, first-time poster. I'm knee deep in a full restoration of my 31 footer and have a question that I can't seem to find the answer to and was hoping anyone could help. I have replaced my old Univolt converter with a Progressive Dynamics Inteli-power PD9260 unit and begun the process of switching out the glass tube fuses for the blade type. Regarding the wiring coming from the 7 pin socket, what wires do I put on fuses inside the trailer (not the TV)? Is it just the lights? Or do the brakes (blue wire) and the power lines also get fuses in the trailer?

Thanks for the help!
