Dunno how much this helps for the E46, but we identified the innervation point of all 13 wires in the E39 trunk wiring loom over here.

If you don't get an answer specific for the E46, the technique we used to identify the wires' innervation points should be useful to you also.

In addition, the problems that occur when the end points were enervated (by the broken or shorted wires) might also be of use to you.
