280/110/Weber vacuum lines

Dear Friends:

Nearing completion of my 74 280 engine reconstruction job.
A few weeks ago, I bought a very clean Weber carb replacement kit via Ebay.
I thought that if I got a reasonable deal on a replacement carb, I would replace the carb, too, while I had it all out anyway. The solex 4A1, to my knowledge, had nothing wrong with it (yet) , but I really like the idea of better milage as well as reliability and perhaps performance.
This car has an automatic transmission.
My question is this: With this 38DGAS in place, the vacuum lines situation is greatly simplified. The lines that were used in the stock situation no longer have obvious homes..Not having any written instructions, I assume I plug everything, via a multifold connection, into the single vaccum inlet at the adaptor's base. Or is there a better, accepted arrangement?

Thanks,
Will
