EDIT: Just tested, connecting B/P - B/O from the grey connector is working !!!
Thanks @Sjonnie
@Dallas: i just see that my old adapter is not wired (for my car) !
On the adapter, there are just 2 wires on the central (green) part of the connector...
But from the car connector, the middle part is NOT wired... so i don't need to plug this adapter...
Also, after a (long) testing on the road today all is fine except... Radio !
Do the Rover 75 antenna need to be powered ? i can only get 2/3 FM stations, which is very low (even if i never listen radios, it can be useful sometimes, like the highway radio info.)
Last thing, i have read on this forum than "ILLU" wire is useless but it's not the case.
Edit: Just see this connector, look like a GPS one but my car don't have GPS (it's a "pack luxe" but from benelux, which don't have GPS)
This connector is used on my original radio
