Vacuum Hose Diagram needed 86 Civic GL

[Sarcoise]

Anyone know where to get a vacuum hose diagram for a 86 Civic GL 1.5 MT? Someone before me rebuilt the engine and now I have the intake off and see where a hose was supposed to go yet I have no loose hoses. Its a small hose on the driver side near the firewall that comes off the main vacuum tree - on the bottom is a plug for a hose and it is wide open. My car recently failed emissions - I was told to look for vacuum leaks and this is what I found. I can take a picture if that would help anyone, but I would like to know what is supposed to go here. Thanks in advance for any help.
