Check with BMW if that car had a recall, there were quite a few that had battery cable and rear light replacements under a few different recalls.
The person who bought it new didn't go for the foldable seat option, quite a common option on german cars.
The various leads on the battery are for the IBS and for the blowable link. The IBS monitors load, drain and state of the battery and helps the car regulate charging. The the blowable link if part of the airbag system, if you roll the car it will blow and disconnect the power to the car.
