So I have almost everything put together on my car, except this last vacuum connection. Of the 2 lines coming out of the ISV, I have the one leading to the Venturi Tube connected, but can't locate where the other one connects to. The Clark's garage diagram says it leads to the intake pipe, but I can't seem to locate it. Please tell me I don't have to pull the intake manifold again...

Any pictures or diagrams would be greatly appreciated. Also, this is for an 85.5 NA. Thanks in advance.

Unless I misunderstand, The ISV Vacuum line goes to the intake air boot at the underneath-bottom by the bend.

EDIT: A small plastic connection tube is used to connect.

I think that's the one I have connected. It's the rear hose I'm confused about.

Here is a vacuum line diagram from Clarks. It is for the 85.5 but may help.

EDIT: I found a picture of the ICV and hoses. The long hose goes to the rubber intake air boot-underneath.
The short hose goes to the intake manifold.

Thanks a lot guys. This was really helpful, but it turned out I had to remove the fuel rail and intake manifold to connect the last hose.
