Outer Limits 4x4 Board

Hi there, basically i was tracing and cutting out the split leaking ends of the vacume hoses under the bonnet in an attempt to get the cruise control to work. I found the vacume hose that goes through fire wall was disconnected and just hanging above the pedals where your feet go and am buggered if i can find where it attaches.
Any guidance much appreciated. Damn thing frustrating the hell outa me.

There are vacuum switches on the brake pedal and the clutch pedal.
That is what my Disco1 has at least.
