It goes to the big port (with the metal tube in the silicone version in the pic).
Just above the turbulant flex joint...
The oem bov return hose is shaped to meet that port, once you get it in place, it should naturally meet up.
Get a zip tie or clamp on the hose, douse the area in WD40 or a similar slippery lube, remove the short fat bit from the inlet and jam an XL size screwdriver handle up the inlet pipe to remotely push the port into the bov return hose, then do up the ziptie or clamp.
Using that method, you may be able to cheat removing the tmic, maybe.
But do it asap, massive pre-turbo inlet leaks are not good.
