Egr delete and pyro question

Hey Im just about to do the egr delete that I got from H&S. There are three block off plates, but none have a Place for the pyro. Just curious if I have to tap the small, medium, or large plate?
I'm using the pyro that came with the minimax correct?or the one out of the DPF?
Oh and how do you "burp" the coolant systems
Thanks guys
Mat
