Well I'm kind of stuck here.
My "new" winter car was fitted with the NCDC 2013 head unit and the NAV-display. It seems that when fitted with this the wiper stalk is a bit simpler with no buttons to change the display messages.
I have removed the NCDC 2013 unit to be replaced more modern stuff and also put in the simpler display. The display itself seems to work alright but with the original wiper stalk I can't change any messages on the display.
From my old Omega that I scrapped I got the wiper stalk with buttons (Got the display from that one too) but that one has an extra connector with 5 wires going to it. But the car doesn't obviously have the connector to the wiper stalks extra connector. I also suspect that the wiper interval control are in some of those five wires.
I guess that the display controls are on the NCDC 2013 unit and then there must be some wires there that I could hook up my new wiper stalk to.
Is this possible??
The original to the left and the one to the right I want to put in.

Thanks
