Default 2004 S80 T5 brake booster vacuum problem

Hello,
I'm working on the vehicle where it had a straight vacuum hose from intake manifold to brake booster installed temporarily.
Installed the vacuum pump and vacuum hose switch into the vacuum line, but I'm not hearing the vacuum pump turn on, and the break pedal is hard now. I will check fuse 11C5 which is 15amps and should be feeding the pump, but I'm not sure how the vacuum hose routing should be, could not find any diagrams.
