"How did you do it on yours? how many holes do you need if I do need to do this?"

Bryan,

I punched a hole in the SCAT ducting that feeds cabin heat to the firewaill.  You have to crack the cabin heat valve enough to get the bundle of lines (1/4" plastic) into the cabin.  I used a bulkhead fitting to get into the upper plenum chamber.
