Ford Transit Custom windscreen heater

[silvercircle]

Hello,
does anyone know for a Ford Transit Custom EZ 12/2017 in which I've retrofitted a windscreen heater, where I can unlock this, or what coding is necessary. Everything is installed but unfortunately the windscreen heater is not running yet. Unfortunately, the AS-Built Editor of UCDS is not yet available for this model.
But with Forscan I get into the BCM, but I do not know the parameters that need to be changed.
greetings
Thomas
