i tried installing these last night and they fit alright, but now i dont know how i should wire them, i need them on a switch since they are blue and illegal to be on all the time or else i would connect them to the lights for the plate, i have underbody lights and there is a wire in my trunk i could tap into. but since the wires are up in the hatch, how can i connect them with out taking most of my car apart? any help would be appreciated, thanks.
