That spot is used to indicate what gear you are in on the ATX, and in my car is just dummyed over with a plastic panel, You should be able to pull out the shift up light and splice it into the harness without a problem.
I'll check my local yard for you dutch...And do you still need a mirror glass?
BTW, I built a homemade A/F guage using a 10 LED bar and mounted it in the dummy panel, It looks OEM....Pics someday if I ever get a digital camera.
