B18b1 intake manifold on B18a1

As the title state I have a obd2 b18b1 intake manifold on my b18a1, I need to know where to run my iacv hoses. I know one runs to the block beneath the intake manifold, and the other runs to the side of the intake manifold underneath the throttle body. My question is where do I run the hose that usually runs underneath the TB beings my new intake manifold has no such provisions.

I have searched and have found nothing besides how to run vacuum lines

All help will be appreciated, thanks in advance.

if im not mistaken, i believe it would run to the upper water-neck attached to the head… Look for 1/4in water hose fittings

ok. i dont have one on my current head but i may have one laying around. thank you for the help.
