how to wire up fail safe to turbosmart eboost sreet?

[Alaskan EJ20]

i have an Eboost2 from Turbosmart and HFS-6. To wire the boost cut in need to find the wire from the controller that sends the signal, cut it, then hook the brown to the solenoid and the white to the controller??

What about the "optional wastegate controll" two wires coming from the flow control module. What do i do with these.
thanks gabe

Yes on the first part and ignore the FCM wastegate wires.

Now for the tough question. Which wire sends the signal on Eboost2 the brown one or grey one?? i have some searching to do.
