you need to take a pressure tap off the compressor housing on the highest pressure point as possible for best control like this.



if you have a 3" inlet and 2" outlet compressor housing you may have to weld on a bung like i have had to,otherwise you can only pick a point up near the discharge end of it.

if you intesnd to keep the stock boost control solenoid,you will also need to tap it into the inlet side of the turbo aswell.

garrets dont have built in dump valves like the stock turbos do so you will either have to run a bailey dump valve or an after market recirc valve.either way you want to run the stock hose to the dump valve to allow it to work properly.
