You have the head and body morph packs from DAZ, right? As long as they are all installed correctly, they should kick in when you click on the appropriate MOR or INJ pose in the character's Pose folder. For example, my own character, Luna Gothica, has a MAT-INJ pose combined, which will morph the character and load the appropriate textures. If the morph packs aren't present, or they're in the wrong folder, subdirectory or runtime, the INJ won't have any effect, or it may give an error message.
