I didn't use an 8 gauge wire to E3 nor did I advise the use of one in
this thread, did I?

I doubt that the trace inside leading to E3 is thin, but that is just
my supposition based on conjecture "why would VW make a thin bit of
brass in there, it needs to be of some reasonable thickness to be
somewhat self supporting for ease of assembly"

If VW later increased wire sizes for certain points coming off the
panel, did they also increase the brass size on the inside of panel at
those points? I don't know, do you?

I have a small aux panel under driver's seat. It is connected to my
aux. battery. The panel feeds, on separate wires and separate fuses:
the kitchen, the stereo headunit, and the E3 main panel point.

My stereo headunit has it's own grounding point.
