for Terry,
the wiring diagram you posted way back for the 2-6-0 tender plug has the right rail and motor + wires swapped.

If anyone is interested
Laura ? at Bachmann contacted me today.
She said the tech told her I needed the connector with the 8 inch wires

thanks for trying to help.
but you are not reading what i am posting
go to On30 0-6-0 steam parts, scroll down on parts to the bottom you will see a 6 wire engine to tender replacement harness S25209-11.
that is not a 2 and 4 connecter.
the HO steam engine parts show 2 different 6 wire tender harness 10547 and 10548 one says large the other says small.
the HO tender plugs are the ones i am trying to get the correct one to plug into the S25209-11 engine harness.
i still have not received any answer from Bachmann.
Willis.
 

Thanks Tom,
i got the broken piece out, tried to solder to it but in the process i lost that tiny connector.
i dropped it twice and found it both times but the 3rd time i have no idea where it went.
i listed the part numbers in the post of the only 2 HO plugs that look like they may fit,
but they identify them as large or small.
ordering both at $9.14 each plus tax and shipping, then using only one of them is wasteful.

ps i sent message to customer service this time maybe ill get an answer

i broke a wire out of the tender plug
parts only shows the engine harness as S25209-11.
i cannot find any tender harness listed anywhere in Bachmann parts store.
i found a listing for Connie 10547 and Connie 10548 one has 8 inch wires the other has 3 1/2 inch
wires.
i have emailed twice called twice with the phone i got leave a message and phone number we will contact you.
i have not been responded to either way.
all i want to do is get the correct part.

Hi, Biggie
i am confused
you said engine ran with old module?
what does that mean ?

 you are saying you have the same DCC system that engine ran correctly with , is that correct ?

where does one find flex track switches

you need to find out if they are led or incandescent bulbs before you connect to power

go to micro trains for n coupler kits

thanks Fred,
i went to parts and On30 but i didn't go far enough.
Willis.

please tell me where On30 kitbash parts are located.
Willis.

correct, the jumpers are for DC use.
Willis

You cannot power the switches from the EZ command control.
Like Len said, you need separate power supply. as in a (wall wart)
Willis.

the ones i had years ago, you slid the switch one way or the other then quickly pushed down and released the slider.
power only when pushed.
Willis.
