Help with friend's 348 project

Hello. I'm just trying to help a friend out with he's doing on his 92 348 engine. I've checked out some pics on this forum but cannot find what I believe he is looking for. He says he needs info on the routing of items under the intake manifold. "the vacuum lines, vacuum switches, and the 2 ground connectors." They are all there, just needs to know where they bolt/connect to. Like I mentioned, the pics i have found here on the forum of under the manifold are good, but don't show them connected. ANY help is appreciated. From him and myself ahead of posts, Thank you.
