Again the rules are very simple.
#1 with any TMCC or Legacy base, there is a special power supply that has a ground pin. That must be plugged into a properly grounded outlet. This is because the ground wiring in your house forms one side of the TMCC antenna from the base.
#2 The base is then just connected to the common outside rail of your 3 rail track system. Most systems, even with blocks, the outside rail is usually common between different loops of track. Again, bottom line, just ensure that single wire from the base post is connected to the outside rails of your track.
