Steve, my red center track power wires from the 6 blocks go to the Atlas Connector on the right side....a single red power wire goes from the lower right hand side of the Atlas Connector to the +side (red) of the MTH terminal block...did not use a ground here from the Atlas Connector. In addition to wires from the 6 blocks going to the MTH terminal block, there are four other red (power) wires and 4 black (ground (wires) from track connectors on the main tracks, all set 6' apart.
A single red and a single black wire go from the MTH terminal block to the "A-U" of the ZW.
