Ford Battery Monitoring System (BMS) Explanation

[colinl]

One takeaway is to not wire anything, like a ham radio, or dash cam, straight to the negative terminal.

that's in the owners manual and relatively known.

I've found that when someone mentions connecting directly to the negative terminal or posts pics showing it, if others point out this issue with the battery monitor, they generally do not correct it and move it to a chassis ground.
