vacuum line to turbo

[JSD69Vette]

can someone please let me know which side of the vacuum lines from the Y goes to the actuator and which side goes to the turbo? This Y splits and one side is a straight shot the other goes off at a 45* angle.

Thanks for the help.

Straight from turbo compressor housing to wastegate solenoid...

Some may advise that if you're not running a stock set-up, then you should run the hose in "test mode". Which is running one hose from the turbo to the wastegate and bypassing the actuator.

the 45 branch goes to wastgate actuator , the striaght end with restrictor goes to turbo compressor cover , the other end goes to the wastgate solenoid on valve cover
