When holding the metal piece with the wires pointing UP and the bulgy sides of the metal piece facing you, the order of the wires in my car was from left to right:
1] Fuse 25 wire (this is the one that generally provides power with ignition to the other 4 wires)
2] Headlight switch - this goes to the headlight switch
3] Left parking light(corner) / left taillight
4] Right parking light(corner) / right taillight AND interior dash lights
5] Low beam relay - goes to low beam relay
I just did this to my 94 318i and it was just the opposite. When facing the metal piece with the bulges facing you the far right was Fuse 25 then headlight switch.
Thanks for the write up
