Got all wiring mounted, an additional toggle in my little toggle-cluster design, and demonstrated the theory and equipment. Appears mounting of the motors-gears-braces will be my primary concern. Tomorrow I'm going to see if the original sunroof-motor location can be worked out somehow... Never thought mechanical-physics would be such an issue for installs. Seen it on TV, never assumed I'd have the ambition to attempt to add any physical motion to my projects. I am taking pics as I do it, anyways, wish me luck for tomorrows attempt..
