This small hole idea sounds great for repairing the foil.  But I plan to
eliminate mine altogether and make a wiring harness like Jarrett did here:

(for all the plugs, I figure I'll just cut their rectangles out of the
foil, and solder wires directly onto the metal tabs)

I figure the result should be much more reliable (and trivial to repair if
any problems developed).

Not a fan of the foil...
