So, I put down an AA Energy Face, one of the 4 Phantom Faces in AA, put a plug next to it and it didn't connect. Yet Redstone Fluxducts connect just fine. O.o This is for Fluxed Networks version 1-12.2-4.0.14-31

how do you unblack list it

It was blacklisted by default. You can remove it from blacklist in config if needed.
Well, why do you need it? why don't you use flux point directly?

Space, since the device is a powered spawner buried in the floor with redstone going to it from the bottom side and the sides are the ground the top is, well, sticking into the main chamber so running energy fluxducts to it wasn't possible. It was either redstone phantom faces or energy phantom faces. Or install Ender IO and deal with the changes from 1.10.2 >.<
