What updates do you mean? Firmware or google apps perhaps?

If so, both of these can be set to only update via wifi in the options

Firmware: settings>about phone>software update>wifi only
Google Play: settings>update over wifi only

if you are referring to sync then I don't know of any way to specify wifi only
If you mean your widgets (eg weather etc) then this would depend on each one's options

 

4.4.2 seems to have moved or eliminated
the update only on WiFi options for
updating applications.

Did it move, or was it removed?
