Had a little peek (and fap) before I jumped on the treadly this morning. Needs more daytime pics for sure.
I got mine from an LGT forum buddy in the USA. It was a swap... (for Jakes Liberty letters

plus I bought some cool stuff from this guy )
The black swcs are off either GRB or GVB STi or WRX...

The stock LHS SWC's I had on my Lib are 6 button, but the black SWC's I got are 5 button, so I'll just swap the black 5 button fronts onto the 6 button switches...
This worked fine but I'm up for swapping out if anyone has black 6 button left SWC type.
Basically the 5 button left SWC is for MY08+ afaik with the phone compatible stereo. The RHS cruise buttons are the same.
The MY07 & MY08+ SWC harnesses are slightly different, but the buttons, covers, rubber switch pads and circuits are all interchangeable.
I believe the black SWC's are available from OEM spare parts suppliers, I'll google up the parts numbers or ask at Makin and Luby.
