Lionel Model 364 Conveyer (Log Loader)

Bought this for my Grandson last Christmas. It worked fine. However they moved and we ripped out all the wiring.

Now I can’t find the instructions and need help on how wire up to A, B, & C terminals from the transformer.

Thanks for your help in advance from a doting Grandpa.
