Linking .bvh file to a mesh body shape

I’m pretty new to blender but I’ve imported a .bvh pose into blender that I created myself in an outside software.

It comes in as the basic bones.

I also imported a mesh human body (collada file) and the body shape is in the basic T pose.

I would like to use the .bvh pose with this body shape so when I go to the 2nd frame of the pose the shape will form with it? How do I link them together? Any step by step tutorials on this?

Side note the mesh human body file I imported already comes with a T shape armature. I would assume I need to delete that one out?
