Walters O Scale Palace Movie Theater Wiring

[Trainpassenger]

Need some help on rewriting some of the circuit boards wiring connections that broke loose when I built an interior For a WALTHERS O SCALE MOVIE THEATER.

Does any one have a schematic or could take a picture of a completely wired circuit board. My marquee and backsplash still are wired and work.

But the LOBBY LIGHT, PALACE, AND THEATER signs wiring at circuit board have come loose.

Tried WALTHERS but could not help out

Thanks for help
