That red wire probably goes to the exterior lights. I don't know about removing the carpet. Losing a lot of insulation that way.
Yes, I am now pretty sure the red wire is the hot wire to the exterior camp lights, and the green wire I found is the hot wire to the rear floods.
Good point about loosing some insulation by removing that piece of carpet, also a place that could form some condensation. Will be replacing the carpet with something, not sure what yet.
