Trick Flow Box R intake vacuum routing?

[NewToFord]

I am putting on my box R intake this weekend on my 408. It has 3 vacuum ports on the side. It's been awhile since I took my other motor out. What should I connect these to? Does one go to the pcv? vacuum tree? I can't remember. There is no egr or smog stuff on the car. Thanks for the help.

PCV, fuel pressure regulator, brake booster (vacuum tree).

Those ports are strickly vacuum and you can route your hoses however you need to. As long as you are getting proper vacuum where it is needed you are good to go.
