Ahh, then it might not be the ‘open’ module, it might be the pioneer/fiat coded one, I tried the pioneer/fiat module but it would not work, I ended up using the
Connects2 CTSFA010.2 Stalk Adapter for Fiat Ducato 2012> 2014 module and it worked fine.
Basically it depends on whether fiat set up the interface already for a pioneer unit or whether they left it ‘open” for any unit.
They year of the van might also be specific to matching the module, as fiat changed the ecu bus around 2015/2016 I think, in the end it’s a bit of trial and error.
I’ve got a New spare pioneer/fiat module (Connects2 CTSFA008.2 Steering Wheel Stalk Control Adaptor For Fiat 2008-2014 )If you wanted to give that a try I could send, if yours is a later year it probably won’t work as ecu bus changed, if it does works then you can have it for £30, if not just return it, if that helps ?.
From your position I think it would be worth just fitting the clock spring, then fitting the connects2 and see if it works, going back to what I said earlier, mine worked whatever setting I had the multi ecu programming for the wheel set at, so I think that bit may mot be needed, just accepting the phone buttons don’t work.
