tpi vacuum hose routing

Hey guys, i need some help, i did a search but i can't find a matching diagram for my car, 1989 5.7 tpi auto trans.I have a bunch of small vacuum hoses and a small black check valve and i'm trying to figure out the routing. one thing that is confusing me is that all of the diagrams i see show two lines comming from the egr solenoid but mine has a two into one connection. The only thing i'm sure of is that one hose goes from the pass. side on the rear of the plenum to the f/p reg.the rest of the connections such as the egr valve, the other small connection on the plenum,the connection underneath the throttle body and the check valve i have no clue. The previous owner tore all this apart so it's possible he has the wrong egr solenoid connection.
Thank's for your help.
