What is this and do i need it it is not hooked to anything but does have a black wire connected to the bottom bolt. Looks like a ground can i just take the box off and put the black wire back under the bolt?

without even having a pic, the only box i know of with a ground under the bolt is the voltage regulator, and yes it is needed
 
well that expains it, it cuts any voltage over 12v for the lights
no lights = no regulator needed
