dual crossing gate wiring

[DAVID L SYMES]

I have the dual crossing gate # 461214, but I don't have the wiring instructions, everything works but not sure how to hook it up, it has the two clips that go under the track and a longer grey wire that goes where ?

If I remember right, there's a 2-conductor grey wire going to each clip, and another 2-conductor wire that goes to the accessory terminals of your power pack for the bell. The clips go under an adjacent track to either side of the crossing, with a tie on top of the contact spring.
