ISO TBI vacuum digrams

[Overthedge21]

I have an 87 v10 Silverado. It's missing many vacuum lines, as well as has some it doesn't need for egr ECT. While I'm rewiring it, I'd like to get the vacuum lines straightened out, and was wondering if anyone on here has any diagrams for the lines, as I cannot find them

Now will this be effected by the fact that the block is not correct? The block is a pre 87, and there's no air pump or ac pump on it. Will this be an issue for the vacuum system, can it be worked around?

Nothing will be any different except you need to plug the J port on the TBI.
