Hey everybody! Back story: I tore down a large HO layout years ago owned by a deceased gentleman and did not have a lot of time to trace everything as the house was being sold so I just cut wires everywhere to get it all out of there. I am now in the process of reassembly. The picture I attached shows the parts that he used to control the snap switches via a Snap relay with the buttons on a control panel. Can someone give me a clue how exactly this all gets attached together to work and how to I get power to it. This was all connected at one point and worked together. Sorry for all of the questions!
