MTH Railking Xing Gates

Anyone have any idea how to wire the Railking Scale Crossing Gates (item 30-11012) such that they don’t have to use an ITAD? The instructions say to connect two of the wires to an ITAD, but this prevents me from running trains in both directions to prototypically trigger the gates. I have the crossing flasher w/bell set, and they are simply connected to a lockon in an isolated track block. That one works flawlessly with trains running both ways. Is there a way to make this possible with the crossing gate/signal set?
