Thanks,
I'm checking it out now...
I never heard of this. I saw you mention it in an older post and didn't know what you were referring to.
Now I see...
I checked the wires to the license plate lamps. 1 side had exposed wire so I covered it.
There is a clear cylindrical fuse between the left and right lamp wires. I see it on the schematic too. That doesn't mean a lot because I don't know what it means.
What kind of fuse is it? Won't it probably need replacing by now?
