HUD Retrofit

[spacey]

Hi im about to retrofit HUD into my v90 t8 my18. i have recived all the parts as is folowing 

HUD dashboard cover : 31417204 
HUD Module : 31687417 
HUD mounting screws :30640826 X1 
HUD mounting Screws : 31109118 X2 
HUD Repair teminal (conector without cables) 31384466 
LVDS Cable (from dim to hud) 31438200 

i bought my lvds cable from aliexpres due to volvos priceing being redicules for that part

now to my question. do anybody have the instruction how to remove the hole dashbord in an v90 t8? 
And if someone have the correct wiring diagram for volvo v90 t8 my18 the whold also help. i only have acces to volvo 2024 wiring diagram and it might not be correct to my car.

AFAIK HUD also requires a different windshield, not just dashboard components.
