The old wire color nomination in german thinking...nature related:
BR = brown (german "braun"), which stands for soil->earth->ground
GR = green (german "gr??n"), which stands for plants->life->energy
So any wire marked with "BR" or "BR - ?" should be connected to ground.
Wire 31b is marked "BR - SW" (brown/black, german braun/schwartz) indicates it is connected to ground. To verify 31b disconnect the br/sw wire and measure the voltage between the loose end of the wire and batt+. Should read 12.3V with starter button pushed and 0V otherwise.
Here's a diagram for the relay: http://forums.bmwmoa.org/showthread.php?t=61255
