  Jay,
  I just drilled out the hole the size I needed.  Start
  small and increase the bit size slowly. That helps
  punch through the Stainless Steel. Once I could get my
  Dremel drum sander in the hole I used that tool to get
  it to the right size. I burned several drums in the
  process.
  I then used a piece of fiberglass tube and bonded a
  1 " length into the hole (tight fit) with high temp
  RTV. I used the hole to pass many connections through
  the firewall during const and when I was done I filled
  up both ends with more high temp RTV. I have since had
  to pick out some of the RTV to run another wire. You
  simply RTV the thing back up. Neat, cheap and easy to
  do... You can also make a stainless patch and screw it
  to the firewall to cover most of the hole to help keep
  the fire out.
  I am certain there are more sophisticated ways to do
  this but this worked great for me and if you do it
  right it looks nice....
  Hope that helps...
