    So from zone 1 hit the valve then t-stat and back to the other side of zone 1 same for zone 2? T-T sends signal to boiler to fire

    No, I don't think so.

    You need to get 24 volt power from the panel, or from another transformer. If I remember correctly, the 24 volt power is toward the top, on the left side of the panel. Common to the zone valve uninterrupted, hot, to and through the t-stat to the zone valve. The end switch of the z-v will be used to close the connections on the panel for the circulator. Your boiler is energized through the x and x terminals.
