Default Cruise Control Vacuum Hose Location

1999 Civic Si D16Y8 (Canadian)

Tried to use my cruise control yesterday and realized it will activate but never hold the speed. Digging in the engine bay I found this vacuum hose going from the cruise control unit but cannot figure out where the hell it plugs into.

Anyone able to tell me where it plugs in? Or a picture for reference?

Attached a photo showing the line

Thanks

There is a little nipple jutting out on the back of the intake manifold, if your looking at it from the front, is on the right side, almost underneath the surge tank, that goes to the vacuum tank, and TV the vacuum tank hose, that connects to the actuator. Pic is a y7, but you get the idea

Thank you both. Both the directions and the forum post that got linked helped a lot, managed to find it. Surprised I didn’t see it when I looked but oh well.
