In my MY2020 Ducato, the radio has de wirings for rear speaker, I found that previous Ducato models had a connector in the passenger pilar, but I can't find it in mine, where do these wires go ?

Your link shows that the van is likely fitted with one of the motorhome builder's Pioneer radio/sound system packages.
That means that the van would have been ordered by the motorhome converter with what is called the radio preparation option - basic wiring loom for an aftermarket radio. The wiring in vehicles ordered from Fiat with the radio preparation option is different to the wiring in vehicles fitted with Fiat factory radios.
The rear speaker wiring preparation socket is as far as I know only available with the factory fitted uConnect radio, which is connected through the canbus. Vehicles with factory radios have different radio wiring to vehicles supplied with aftermarket radio preparation as above.
When rear speakers are connected to the factory radio via the optional wiring socket in the door pillar (the conversion socket) they then have to be enabled by programming the body computer, which alters the configuration of the radio unit.
Fiat's explanation for the rear speaker preparation option states "Rear speaker wiring prep is available as an order option. Included with this package is the up-fitter interface connector. This option cannot be added at the aftermarket or by the dealer."
The website for your van shows that the rear view camera is probably either part of the Pioneer radio pack or the motorhome converter's optional "Serenity Pack". That means that the installation has been custom provided by the motorhome converter and is not standard Fiat wiring. If your van has the Pioneer radio, possibly the installation manual for that unit would help you, otherwise you would have to ask your motorhome converter Dreamer.
