With no voltage, the valve should be open from intake side (bottom) to alda side (middle). With 12v, it should be open from middle to vent/top.
No, the turbo wastegate on the '91 SDL (603.970) is the same pressure-actuated as the 603.96x donor.

The ground is switched, as far as I can tell the ground should not be switched but it is, its really annoying to find electrical issues without good diagrams
