Toyota Trucks: Vacuum Hoses Don't Match Shop Manual

Two pairs of the myriad of vacuum hoses on the right side of my 3VZ-E are
hooked up reverse from what the shop manual shows. They are the ones that
are connected to the forward two VSV's, the ones for FPU and EGR. I was
very careful in labeling these things when I pulled the air intake and, when
I went to put it back together, I checked it against the manual and
determined that these two were reversed from the configuration shown in the
manual.

Which should I go by: empirical data or the definitive source? I haven't
had any fly-by-night folks work on the truck but it is possible someone
(even at the dealership - gasp) could have buggered it up as I have found
other things on the truck that aren't quite kosher. On the other hand, I
have also found (minor) things in the manual that are not correct.

Maybe it doesn't matter. The pairs of hoses are going to the correct VSV -
it is just the input and output are reversed. But, if anyone knows, I would
like to hook it up the correct way. Currently, I have split the difference:
I hooked up one back the way I found it and the other according to the shop
manual. Hedging my bet, as it were.

Thanks in advance for any words of wisdom that you can pass my way.
