BB-cuda,
I'm not 100%, but I do believe the turbine change over vacuum can retracts the rod with vacuum, so that would be aft, toward the rear end of the car.

Thanks for the confirmation on WG behavior!
Also, confirmed, the turbine control valve at rest is extended allowing exhaust into the both HP and LP turbos. With vacuum it retracts directing exhaust to the HP turbo.
Likewise, at rest the compressor bypass plate is closed directing air to the HP turbo. With vacuum it opens.
