On the HTV you talking about the RCS the way they look ? and engines do work but dont thing you can get them to show has a engine because it has command it will show the fuel when the engine are engaged

If you want to see how far with it here is test folders 

https://www.dropbox.com/s/se4qu90ge900fxr/ISS and Mir test.zip?dl=1

Unzip and put them in your ksp/gamedata

the mir has to be ksp/gamedata/mir   

or some files will have to be edit

If your going to play around with fixing or change things in a mod theres a couple of plugins that help with some things https://github.com/linuxgurugamer/NodeHelper

and
