Installing Extra USB-C Chargers on 32c (2012)

[UAT Norway]

For someone with limited knowledge of electrical systems, especially the 301 panel on my 32c (2012), could someone provide a brief explanation of how to install 2 additional USB-C chargers? One should be located near the helm, and the other in close proximity to the 301 panel. Do I need an additional relay? Which of the F switches should I use? Where do I connect the positive and negative cables? Additional fusing on the cables? Etc.
As you can see, I need a basic course on this

Hi UAT,

I have a later model en not the 301 panel fitted with the relays anymore, but can give some tips you may find useful.
Pick one of the F’s which are not occupied, very likely they are equally fused. Connect your “+” of the USB’s to the free connection of the chosen “F” on the board and link your plusses through. Connect your “-“ of the usb to the common “-“ rail and you are done!
Seems a simple job to do and I would not propose any additional fusing as it is already fused on the panel
