Vacuum to my cruise control

[bobfist]

Hi!
I wondering how the vacuum was connected on the cruise control unit on my 69 rt/se.
I need the three vacuum port nipple on the manifold.
One of them goes to the brake booster, one of them to the ac unit, and the third one to the cruise control?

Cruise control USUALLY takes vacuum from the brake booster check valve extra tee.

I guess depending on the check valve kind you have

I meant the ones like this:

1969 B-bodies the cruise servo gets it's vacuum from the power brake booster ck valve .
BUT, if I remember right the servo has a second fitting that comes off of it that connects to the brake switch
The vacuumn dis-connect style of brake switch 'can be' extremely difficult to locate.

Thank you for the answers, i saw a picture from the factory bild instructions.
And there they show One of the Cruise control hoses going under brake booster to manifold.

sorry, I don't remember the actual routing of the vacuum hose. It was probably close to 15 years ago I pulled this switch off  a 1968 Charger R/T parts car

If i connect the brake booster by it self to the maifold and the  ruse control unit as well to the manifold, would it be wrong if you look at the two pictures below
Looks like they made to diff ways?
