Just gone out to get some pictures but it started raining so I only managed a few. In addition the position of my diverter valve may differ from yours, I also notice you have had your n249 bypass done already so this will serve as a suitable guide.
Here is my n75 valve (it's a boost control solenoid and connects to: 1) the turbo intake pipe 2) the turbo actuator 3) the boost pipe)

Coming off the n75: top hose leads to the turbo actuator, left one leads to the charge pipe (as shown in the picture below)

Under the inlet manifold you will have two small nipples for vacuum, one goes to your diverter valve and one goes to your fuel pressure regulator (as pictured below)

Above picture shows the vacuum line going from the inlet manifold to the fuel pressure regulator

The above picture shows the other vacuum line from the inlet manifold going to the diverter valve.
