so i have either a bad connection or a short in my overhead lights, but i cant get the dang thing off, so i was wondering if anyone could help me out, i also found a random wire in my engine bay that's disconneted i think it's a engine ground wire but im not quite sure so if somone could tell me what it is and where it goes that would be great, ive got pictures attatched of the interior and the random wire in my engine bay.
