The guy I bought it from didn’t know either, had it 6 months he said, believe it to be an old company vehicle but not sure, it definitely doesn’t run like it’s pushing 300k

I don't think there is any wiring correlation from the radio to the flex fuel sensor, but when you cut wires on the lan bus with the battery connected it's never a good idea.
I would take the time and get a meter and check each and every fuse.

Thanks for the advice that was on the list tomorrow after work, once it shuts off it’s kind of hard to get started back
