The FPR is on the fuel rail, and the MAP is on the back of the blower. Both of these need to see boost, so they need to be connected to a vac line after the blower. The BBV actuator is the black canister on the front of the blower. You will need to connect it to a vacuum source before the blower, which is what that manifold (tree) is. This opens and closes the BBV based on manifold vacuum, which is a good thing. Normally on the L67, the actuator is also connected to a solenoid, which is connected to vacuum after the blower. The computer controls this solenoid to force the BBV open for things like traction control. Flashing an L67 bin to the L36 computer has been hit or miss on whether it can control that solenoid or not, so the general recommendation is to just leave it vacuum controlled and not worry about letting the computer interfere.
