1988 Toyota Camry 4 cyl Two Wheel Drive Manual 222k miles

In the process of troubleshooting my cruise control system, I found that the reason my cruise control was not functioning was because of a missing vacuum line. I then checked for vacuum lines that were not connected to anything. What I found was a vacuum line connected to 2 vacuum ports. I proceeded to to disconnect one side of the line and connected it to the cruise control. The question that I have is where can I find a better vacuum system diagram since the one on the car doesn't include everything?

Yes ,The cruise control is vacuum actuated on the 1983-91 models.
there is only vacum system diagram for the emission system under the hood, I do not see a diagram for the cruise control either.
Is the cruise control working after you connected the vacuum line?

Yes the cruise control works fine, I just have an extra vacuum port that I wanted to make sure didn't go anywhere before I plug it up.
