Hello everyone, quick question.... i have an Atlas HO C-424 locomotive that has the light board in it with the dummy 8 pin plug in it. I have a Digitraxx DH121 and a DH142 decoder with a 8 pin quick plug. Can i just unplug the dummy plug in the Atlas locomotive and plug in the decoder? If so, which color wire/pin goes where the white arrow is pointing? Any help or information is appreciated. Thanks!
