I'm about to add mine but I was going to go stud to stud for support, but would like to maximize insulation vs wood support like you.
After setting the wood blocks snugly in the foam (I may have put a little silicon between the block and aluminum to help keep things steady,) I used the rotozip to cut the outside skin using the hole as a guide. Then reinstalled the wall wood and drilled a hole through the inside wall from the outside to mark where the hole was. Went back inside and used the router to cut the hole in the inside wall. Then to answer your question, I put screws through the wall wood into the backing blocks. Makes a very solid backing to screw inlets/outlets to. The one thing you have to do to make this work is, make sure your wood block is the same thickness as the wall cavity. Mine was 1" so in the picture you can see I used two pieces of 1/2", another time I used some 3/4" and 1/4" together. I hope this helps.
