the colors of the diagram do not match the colors of the news stand.
On my news stand hook up/ the red wire of the news stand go to a transformer constant.
the white wire got to the newly made insulated rail.
the black wire goes to the opposite rail which is just a normal rail. pictures below. I also use a button to operate the news stand manually. Yes, the light stays on all the time.
the "red wire in the photo is an extension of the white wire so it is white
