Question about my sunroof switch on the dash of my 78 300D, when depressing the upper portion of the switch it moves the sunroof aft, and when pushing the lower part of the switch if moves the sunroof forward.

This seems backwards, can anyone check their car too see if this is how the factory intended it? It just seems backwards from any other vehicle..

If it is backward, I guess I could just reverse the polarity on the switch or motor right?
