Sorry here's the link again.

It was 240edge.com not 240sxedge.com. Sorry my bad.
As far as the vaccuum lines disconnected, It looks like he disconnected the EVAP canister purge control solenoid lines.
The one on the right goes into the EVAP canister purge control valve. I'm not sure where the other one goes.
The diagram is in the FSM, EC section, page 13. On page 12 you can follow the routing from the control solenoid to find out where the other line goes. I'm thinking it goes back to the purge canister but I'm not sure.
