I will make it a point to document all the wires the next time I'm
there.

Do you have close-ups of the other two metal tags that show up
in the image at the back of the trailer ?
you posted the one black tag, ( OA-3880/MPA ) next to the tailight.
might be helpful to see the other 2 tags...

although, I think one sez "trailer M406E2"  but its not clear..
can't read the lower one at all..
