Hey guys, for my layout I'm using marklin electric turn outs. I'm up to my train yard, and am doing a module type yard where I can attach it to my lay out. I have about 8 turn outs and a double slip switch in my yard that I plan on building. I see this metal piece that comes with the marklin switch packages, what is this exactly used for? do I have to individually connect every switch track to my transformer and switch block? there must be an easier way to do this. I also bought brown yellow red extension wires for my switches incase I have to go a longer distance than the stock wire. Do you guys know what colors attach to the blue and yellow stock wires? Electricity is my biggest flaw with Z scale or any trains of that matter so if anyone has pictures of there marklin wires and electric set ups that would be great. Any help would be really appreciative. If you guys can seriously help me I'll be willing to send a few of you a train or structure of your choice on the house. Thanks guys!
