Great sign but check the size of your building 1st
Miller hit a homerun when they combined the vertical sign with the marque to save us some money. Instead of providing 2 battery boxes and 2 electronics boards, everything runs through one with 2 Y splitters provided. The vertical sign is 2 sided and has 2 connectors on the bottom. When I got mine the 2 were stuck together so they looked like 1 and I couldn't figure out how to plug them in. It seems the piece of paper with that instruction was missing but the customer service department at Miller quickly solved that problem.
The marque is pretty long for N scale, fortunately they designed it so it can be bent, so that helps tremendously. I scratch built my theater to fit the sign so that solved that problem.
