Manual boost controller for 88 sunbird GT.

I need a correct diagram or expenation of how you can install it. I tried hooking it up how i "thought" it should be and I have a feeling I'm wrong.
The only diagrams I've found don't work with the turbo in my car because there is no line coming off the tubo, only the waste gate. In about a week or so
I start working on my car to be road worthy and this is the last thing I'm in the grey zone about.

There are two lines that go to what I assume to be the boost controller right in back of the windshield fluid reservoir.
One line comes from the boost lines off of the waste gate and the other goes to the boost gauge in the dash.

Sorry for the numerous posts but i just read that the stock boost level is 7psi. Is this correct? I wouldnt know yet because i haven't had a chance to really drive the car
and see what it's putting out for boost. I also have a FMIC and thats the only reason i wanna turn the boost up a little.
