Here's yet another picture of a trunk loom (from QSilver7) and a description of weird electrical lighting anomalies which turned out to be due to a classic broken wire.

"I had a CHECK REAR LIGHT warning (last week) on my 540iT and one of the bulbs on the passenger side was not working. After checking the bulbs (swapping them etc) which proved that both worked...I tackled checking the loom (on the Touring it was in the far right tailgate hinge)...there it was...obvious as day...a broken wire (white with a burgundy/brownish stripe). I had to get my needle nose pliers to reach into the abyss to pull the half that was way back up into the roof area of the loom. I spliced the wire back together and all is good again.

Here's a pic of Doug's e39 sedan's trunk loom...and in the "orange box" he found the same white wire broken:"

Note that the LCMIII (in the 2002 E39 anyway) will SWITCH lights when certain bulbs are out (see descriptions from QSilver7 below).
