SeaFoam question

[04 UTTahoe]

I was going to add seafoam to my 04 Tahoe....but there is no big vac line off the booster where I have added it to other cars/trucks. Where should it go in?

Yes there is, search in the proper year section for SeaFoam, there is a huge thread on it with some pictures indicating the correct line.
