65amp wiring/trouble shooting

I went to my car cuz I was wondering if I could find something and I've found this. The part number is 3438713 and the black dot is an indication for the 65amp I guess.

That's just the casting part number.
The black over the Date wheel may be an inspector's mark.

if it hasn't been sandblasted by a rebuilder, the casting year is in the center of the circle.

From what I can see in the photo from yesterday, everything looks like it could be original except for the black wire and device on the output stud.

If the tag is still there, it will be under the head of an assembly screw.
