Apply vector mapping to displace texture? I am using this method for my object texturing and displacement of my mesh.

If you haven't seen this tutorial, the final node tree looks like this 



In addition to this node tree, I am also using a Texture Coordinate node and a vector mapping node and have changed the values so my textures fit properly. The issue I am having is I can not figure out how to, or if it's possible, to also apply that same vector mapping to the displace texture. 

Any Ideas?
I had a run in with this problem and I solved it by applying that displacement texture I want to an emission shader on the object I want displaced. I baked the mapped texture and then used that one as the displacement map.
