Great post that adds to the quality of info available here. I was the one that originated the hole method in the front firewall. Both methods work well, just depends on your comfort level.
Couple of points;
a) An electronic variable speed controller can be installed in the single high speed wire to produce infinitely adjustable speed control.
b) The original resistor pack, generates considerable heat and was located in the air flow of the blower to keep it cool. The replacement, located adjacent to the fuse box, is not being cooled.
That being said, again I say, a great tutorial.
