1989 K1500 Vacuum solenoid line missing

I have a 1989 K1500, 4x4, ext. cab, 350 TBI, auto OD that is giving me some trouble. The PO replaced the egr valve but when I looked at the egr solenoid, there is a port for a second vacuum line. The other port goes from the solenoid to the egr valve itself.
Where does the vacuum line from the second port go? No diagram under hood, the haynes manual is useless, and I cant afford the service manuals any time soon

Thanks,

MC

On my 90, the EGR Solenoid is connected to #1 in Figure #1 in this diagram http://www.holley.com/data/Products/Technical/199R9813-4.pdf

Note that my 90 does not have #4 and I used this diagram since it had a decent picture of the TBI.
