Carey: Thank you for the catalog information and the links to the videos. It is exactly what I had intended to look for.
Fred: My set is #3 according to the sticker near the label. There is a cutout partially visible in the picture of the power connector track that I and my friends assumed was for the power plug. I will enclose a better picture of the hole. Thank you for the this information and any additional that you can provide.
