Hello Christian,
I don't really know if I will get also some connectors. I didn't ask the German lady and now is too late.
As soon it arrives I let you know.
Anyway, maybe some connectors already in the car's wiring could be used if same size.
At worst, a short and flexible multi-wire cable can be used, welding its wires on the panel's PCB internal tracks and connecting each one to the car's wiring through a simple screw bar connector.
This is not the perfect way to do but will work okay.
Hang on for a couple of days, let me get my panel and I will try to guide you after my trial and error experience.
If I am correct, one problem that I can see about your Sedici Valvole is about the oil pressure and temp gauges that are not available on DGT panels.
