Newbie question – mirror

Hi,

I am a trying to draw (in solidworks 2012) a small LED module housing. 

Since the module is mostly symmetrical, I thought I would draw half of the module (on the left side) and then mirror the other side.  But, when the side is mirrored, the wire covers are left out. (see the red arrow in the image) I have tried “selecting the bodies” and also using “all bodies.”  There seems to be something I am doing incorrectly.

Attached is the model.
