Dale,
Not clear what problem you are trying to solve. Shades are self contained units mounted by 2 screws on each end. Wiring appears to run from each shade to switches in driver's console. if you are looking for a fuse, it should be 85 in the front electrical bay.
If it is a TV wiring problem, you can access the TV wiring on the back of the TV by removing the panel at the back of the TV cabinet. See pics.
