Vacuum Hose Routing Diagram

My car is 1983 280zx NA. I'm putting the system back together and didnt take great notes. The diagram posted on the underside of the hood shows only two vacuum hoses run from the Thermal Vacuum Valve although there are three spouts. Any idea where the third one goes?

1 Ts out to distributor and throttle body
1 Ts out to throttle body and EGR
1 goes somewhere undefined (this is the one im unsure of)
