Vacuum lines, 3 or 4 needed

[timpurister]

Hey

On the right side of the cowl there are three vacuum lines going to valves ( shut-off I believe). The lines are coming from EGR, Intake Manifold and Air Pump. Behind the rubber connectors there is one bigger connector that is not attached to anything? Do I have it correctly or am I missing one line. I am studying the EPC 14-125 and only seeing three lines but somehow thinking that I may be missing something.
The connector without a line is just behind the connectors in the picture.
This is a US -94 model.

Thanks

Timo

See vacuum diagram below. There should be 1 source vacuum tube to each valve, and then 1 vacuum tube exiting each, for a total of 3 vacuum lines:

The setup of this is detailed in my Top-End Refresh thread from last year. All of the connectors should be connected to a vacuum line.

Here is one post that details this. Take your time and use the vacuum diagram that the @gsxr provided, and perhaps my photos as a reference.

Thanks once again for your advice. I will follow that.
