Hi all,

So I recently acquired a old pre dcc bachman g scale American 4-4-0 locomotive( Denver model) and tender. I'm dropping in a blunami board I have and came across some questions.

1- the train didn't have a ground connection wire at all and The blunami board does. So, do i need to make one? If so can I attach a wire from the dcc board to a metal nut and glue that to the plastic frame inside the train?

2- I believe the original wiring is 22 or 24 gauge right? I'm going to have to replace some of it for the blunami board.

3- I think front light is a led. A 1k resistor should probably work fine right?

4- does the smoke unit need a resistor too?

Any tips and advice is appreciated.
