Danch this is what my display now looks like with the OBC enabled, maybe it can do more but all I was really interested in was the temp being displayed. When I use the OBC stalk to scroll the display only changes where the temperature is displayed.
Danch, what is a "loom"!!?? "Switch" I think your referring to stalk?
As far as the opening that is required in the rubber cover to accommodate the new stalk, I would not buy a new one because it is already there on the existing one, you just have to use a sharp blade and cut it out. This photo is before the 2nd stalk was addded.
Pdwight if you check out the previous pics in this thread you should be able to see how the new OBC stalk is connected to the control box. If you want more definition in the picture PM me and I'll send you the actual photo so you can zoom in on it. If you have an 03-04 the wiring harness you have to make up is not difficult. With the VW wires no soldering is necessary.
