I had to completly rewire my passenger foglight which is why i had to do the hid, because someone clipped out the wiring, so i ran new wiring, so didnt even think about the single power wire and that ground setup. Just run 2 new wires, or get creative. Go get one of those lil clips that let a wire go in it, clip it in there, and use that as the ground since its grounded out in there? But id just run a wire nad make it look good
Not to hard to find a ground down there
