Hi there, I have a Bachmann GS-4 locomotive the non dcc one and I would like to put a sound decoder into it, but I do not know how to wire one in.  I have put decoders in locos before but these were diesels not steam and they were mainly Athearn locos.  So can anyone know how to put one in.  Because in this loco you can not see where the left & right Rail pick ups are or where the motor bottom connection.

Hi all
It is an old type with a smoke generator and working headlight.
