After a frustrating attempt to get the seatbelt off the driver side pillar, I took the snippers to the plastic cover to access the bolt underneath. I was able to pull the driver side pillar and visualize the wiring bundle running from the overhead cabinet down to the battery bank area.
I pulled the old solar panel plugin access to see if I could use that hole in the roof to run the ham radio antenna cables. It appears the solar cables run through a conduit that won’t be accessible.
The batteries are still charging.
