I am replacing the orange 4 pin connector plug between the decoder and the engine. Several of the existing wires have broken off so I don't know the order to attach the wires to the decoder. I attached the wires in line from the decoder to the pins and only get movement forward and reverse, no lights or sound. I reversed the wiring order and get nothing. Does anyone or Mr. Bachmann know the correct attachment of these wires ?
by the way I'm using the white universal replacement plug since the orange ones are not available But I don't think that should make any difference.
Thanks in advance for for any help. John West
Some years ago I found out two of the wires are for lights and two for motor on my steamers. Lost the diagram.
If the loco has an LED, swap the wire for the light.
I had to trouble shoot. LED's are polarity sensitive.
The two wire plug is for DCC pickup.
I pry the plug oy gently prying with a jewelers screwdriver. Never tug wires.
Some years ago someone posted a diagram.
Good luck.

John, I have a diagram in my train room. I will look at it and post here later.
It turns out that I had a diagram for BLI and Intermountain.
So can't help you.
Thanks for looking
