I pulled the passenger side rear plastics out to tighten down the speaker housings (adapter plate?). When I pulled the panel out I was greeted with this big fat ground wire for the defroster that had 2 splices in it (kind of expecting crappy wiring when exploring new areas) and just flopping around. Anyone know the correct routing for this wire? This is a notchback car, so the wiring is a little different than the standard green house hatch.

Any help is greatly appreciated.
