Good luck with that
Yeah, that's a predicament that will probably require some logic and a little good luck. Unfortunately, no picture is going to solve your problem. However, with a little bit of ingenuity and luck, you can trace the lengths of the harness' tentacles and the bends and contours in those wires and probably figure it out. What you'll find is that BMW configured the three prongers and two prongers so that the harness can be figured out. For instance, if you have same length wires you may be able to note that one plug will be inverted compared to the other one and you'll see that the bends and contours of the wires 'want' to be plugged in to fit just that way.
So, don't freak out that now you have this Octopus of wires to sort out. Familiarize yourself with the sensor locations and try to lay out the wires and note that if you have a three pronger going someplace that there is a two prong sensor, you probably haven't found all the right sensors/plugs because they will be under and behind something that you probably forgot you unplugged.
