Turbo "y" Connection

[PaulRV6]

I have done a search on this and found a descrepency as to how this should be hooked up. Two different threads say to hook it up opposite the other.
Can someone point me to a diagram on this site or GNTTYPE.ORG that shows the PROPER way this should be hooked up? Thanks, I want to get this right without any question.

The leg with the restrictor goes to the compressor housing (or manifold if you want to use that as the boost source instead).

Consider it a lower case "y".
The solenoid goes to the bottom of the "y".
The top of the long leg of the "y" goes to compressor.
The angled leg of the "y"goes to the actuator.

From the solenoid, the line goes "straight thru" to the turbo, y to the actuator. That's how I remember.

s=solenoid

after 2 edits, it looks a little better

lemme try

The restrictor should be towards the line coming from the turbo compressor outlet:

Just digging through the archives, something came to my attention. It seems like the pressure from the turbo should gently split off from the straight part, and not have to do a 160* left turn to the actuator.

This is what the other drawings were trying to show(the following has been edited to reflect the below amendments):

Wait, that kind of resembles scotty's...

Unless your "y" is different from mine, that is wrong. You are correct with the restrictor as it goes to the turbo, but the restrictor isn't at the "bottom of the y".

Since there isn't any actual "flow" through the tube when the solenoid closes, it doesn't really matter if the air had to make a 160 or even a 180 degrees turn. To open the wastegate, the Turbo is pressurizing a tube that is closed on both ends.
