hi all

I have recently aquired a 55 ton Shay.
For the time being it will be track powered, with battery RC in its future.

I have a Sierra board for another Shay that I wish to use.

I believe that the two long blue wires coming from the boiler are the chuff wires. (please correct me if wrong).
My problem is figuring out where to connect the output from the sound board.

Maybe someone can provide some help, preferably with pictures.

Cheers.
