I've only got the diagram for a single plug ECU.

You need the solenoid wired in, and then the MAP sensor wired in.
You should be able to use the +12V from the EGR solenoid for the turbo solenoid, but you need to put the earth to the correct pin in the ECU. If it was me I would just find which pin the EGR uses to earth, pull it out of the ECU connector and move it to the turbo solenoid pin. So if you're a single plug ECU, pin 52 moves to 26.
Same goes for the boost sensor, you can take +5V and GND from anywhere, and then run the output back to the ECU to pin 71 (single plug).
