Well, I am in the process of laying out my track, and I have a question about the DCC on board turnouts. There is a black wire that is not connected to anything, and the print on the turnout says to connect it to power the frog. I don't know yet if it will be NEEDED, but I may hook them up anyway to avoid problems later. The problem is, it doesnt say where to connect the black wire. Where? and should I bother? Thanks in advance. This group is the best!
