working convertible master window switch on coupe

[krazysrfr]

I've been doing a little project to try and get the vert master window switch to work on my coupe, I have everything wired up and in the right spot but the car is treating the master switch as a extra vent switch for the driver side, im assuming ill need to code the car to get it to recognize the new button but I cant seem to find anything on ncs expert relating to that particular switch im assuming possibly the vo might need to be changed but haven't found anything to confirm that, and I've seen a few people get it working by just tapping into the wires but id like to avoid that. any knowledge on this would be greatly appreciated.

You likely need to code FUNKTION_CABRIO to aktiv in NCS Expert so the module knows the switch is for the convertible “all windows” function. Otherwise the car just treats it like another vent window switch. It’s usually in the GM5/ZKE coding. Once that’s enabled the master button should work correctly.
