Brake Servo Vacuum Pipe

[killie77]

Hi
Was changing the Air filter and had to take the Box out to remove the old filter. Replaced with new filter
And put the Box back. It seems I have dislodged the Vaccum pipe from the servo. Problem is I can’t find where it attaches to. Does it go behind the Airbox ?
It’s a 2013 XTR with the brake servo on the right behind the battery. 
Thanks for any help

Engine model?

On my ancient M49(1.4i), that pipe goes to a connector on the intake manifold.

1.6 hdi I’m thinking the manifold would be behind the air filter box. So that may have been where it was dislodged from
