you've totally lost me...
The stock setup (from factory) has the intercooler pipe coming out of the turbo, on that pipe there is a nipple which a vac line is connected. That line goes to the stock solinod, then 2nd line on the solinod goes to the turbos actuator. You will need to disconnect all of that.
Now, run a line from the nipple on the intercooler pipe to the boost controller then have the line coming from the boost controller to the turbos actuator. Theres shouldnt be hoses left right and centre., just two. Make sure you connect the lines in the right way, otherwise it wont work and you'll overboost. Also have a quality boost gauge to check what boost your running, the stock one wont do, its SHIT.
