Does anyone know the correct size for the 2 pin jst connectors on a Walthers Proto EMD SW1200 circuit board. I see two sizes in some comments 1.0mm and 0.8mm. Also I cannot find a source for the 0.8mm jst 2 pin connectors. Any help is appreciated. I am trying to add sound to a SW1200 DCC ready and using a Soundtraxx Tsunami2 TSU-N-18 decoder.
