Rear Shock install

I have A new set of origional equiptment shocks for the rear but I have no idea how to install them. I have read you need to be careful not to break the electronic part in the top but I have no idea even where to start. does anyone have the directions on how to install these or at least tell me how to replace them.Thanks!!

I found the directions in my shop book .They are in and it was just as easy as A normal pair of shocks.
