Vacuum line question

[scoobaru88]

Recently installed ess g3x. Trying to get vacuum lines all done up.
So I have the EVAP going to purple , red nipple goes to a vacuum block (fpr, boost gauge, blowoff, brake booster which has check valve), green goes to catch can then to pass side valve cover.
My question is For the IMRC port- can that see boost or only vacuum? IMRC are currently functioning.
