The pictures I sent are of the Forester and I got the feeling there are alot of differences between it and your Legacy.  Both in wire position and color.  I would go with the 2010 Legacy listing above. 

There is good access to the BIU and with a DMM I was able to locate and verify all the R/S wires needed in 30 minutes.  Seems strange that the Foresters 4 BIU plugs were different colors and the Legacys are all listed as white. 

Going by the < size=6 face=FuturaStd-Heavy>< size=6 face=FuturaStd-Heavy>ADS-AL(DL)-SUB install guide, they call the 35 pin plug, where most of the necessary wires are, connector C and is in the same position as the Light Blue Forester plug.  The Leagcy 31 pin plug is connector D and in the same position as the Blue Forester plug.  They even have the connectors pins numbered.  If the listing above is accurate, the IDatalink install guide should make things easier.  ( It matches OK with location and color for the CAN H & L and the keyless data wires.)

Soldering is fun!
