You wanted to do something right..
so I translate some German blueprint schematics for ya..
and this what you do at home....
does your well stocked toolbox ..
consist of duct tape in various color..
but, I must confess..
TV in Bedroom mounted high in bedroom bookcase..(built-in)
no outlet..= hole in bookcase leading into laundry room and outlet..
works great..
