2022 Tab 320s WFCO Converter AND Fuse panel

Hello!  I will be swapping out current 6V lead acid battery for a LFP 100 AH battery in my 2022 tab 320S boondock.  To do so, I have to disconnect the "inline fuse on the positive solar lead" where exactly is that located?  Also, I am utterly confused as to where the fuse panel is in my 2022 Tab 320S boondock.  I reached out to NuCamp to confirm my Tab 320 has the WFCO converter that automatically detects a Lithium battery. IS the WFCO converter located in the front tub to the left side of the battery disconnect? OR, is it located under the drivers side dinette seat and if so is there a removable panel somewhere?  HOW to I get to this? Why is this so confusing? I am including this picture that NuCamp sent me.  Where is this?  Thank you in advance!

    The Power Center that contains the breakers and fuses is behind the dark brown panel on the front of the driver side bench.  Just press the panel and it pops open.  You are lucky as it looks like you have the lithium compatible converter with a switch to change it to lithium.

    Hi, The inline  fuse for your solar controller will not be located in the WFCO.  If you mean your on board solar lead ,look for the Victron blue solar controller box.  In my '21 320, it was located under the driver side bed/bench.  There will be 4 wires.  Two go to the solar panel, labeled PV (one pos. and one neg.).  The other two, labeled BAT (also pos. and neg.) go directly to the battery.  The positive wire going to the battery will have an inline fuse.  Follow  that wire.  It will have a fuse folder, you pull the rubber top off and the fuse is located under there.  Pull that fuse to disconnect the solar controller from ther battery.

    The reason to go through all this with the solar controller is to make sure the solar controller and new battery are connected properly. The basic idea is the solar controller should be connected to the battery first, and then the solar panels are connected.  
    This gives the solar controller a chance to "read" the battery and determine the basic state of charge.  (You should be able to see this information on the Victron app.) After the solar controller gets the basics from the battery, the fuse from the solar panel is replaced, and the controller is ready to apply the proper amount of any charging needed.
