Need advice on replacing windows

[jrobi70]

Hi thanks for the add. Now to my question. I'm in the middle of changing windows in my house all but four are in brick with I don't have a problem with them but I have 4 that have wood siding on 3 sides and brick on 1 side and I'm using vinyl replacement windows (non flange). My question is Where to set the window flush with the T1-11 siding or out past the siding. I'll be trimming out with PT 1 x 2. Thanks in advance also the siding is being changed out to new T1-11.
