        If your looking to test vacuum you can use the brake booster port on the intake to hook a vacuum gauge to.

          Thanks I just wanted another opinion because I just got the truck and to be honest I was a little overwhelmed by all the new stuff in the eng area.Had been driving a 1989 Astro.
