Radium catch can on non-m fitment question

I've seen people install the radium catch can on non m's before but I still have a few questions no one can seem to answer. I have contacted radium directly but they said they only tested it on the m3 and couldn't tell me. My question is, I've seen people had to plumb in a pcv from o'reilys. Is that only necessary when completely deleting the CCV? Where is the best place to put it? Does the ccv stay in there? What do you have to plug off?
