Just purchased a used Chicago & North Western 4-6-0 TMMC (638042) with no owners manual. I am trying to pair it to my Cab1 however, I can not find a manual supporting the auxiliary code. I can get the engine to run, whistle works, bell rings, marker light works, cab light works, fire box works, smoke unit works and engine sound. What does not work is the headlight and no cab chatter. I have looked for the manual on Lionel web site does not exist, sent them an e-mail no answer yet. anyone have any suggestions.
