Single turbo Doc Race Motiv boost box and mac solenoid (MHD)

[Rodo Lopez 135 ST]

Hey guys I´m new on the page, I am on the procces of making my 135i n54 09 to doc race st 6266, i have doubts about how the motiv boost box works with the mhd, and how is connected the mac solenoid to the wastegates

So how do I use the MHD to control the Motiv Boost Box or does it control itself?
And with this diagram is the way to connect the mac solenoid?

The boost box needs to have the tuning done in mhd. If you have a twin scroll manifold then yes you'd follow these instructions afaik
