You'd disconnect the hose at #13, so that the seafoam will flow through #11, then through the blue dot hose, into the intake to be burnt. But I am not near the car right now to see if that's physically possible.

I would go with the big giant hose that goes through the IACV, to clean that out. It's underneath the black intake tube, and the IACV is one of the most important parts of the intake. Other than that, whichever hose seems easiest to you. The yellow dot hose would be pretty easy, especially if you do have some extra hose the right size.
