Bachmann E-Z Command "black wire"

[Mikezerodelta]

Hi all, Does anyone have a Bachmann E-Z command control centre connected to a Bachmann DC controller with the "Black wire"?
If so could you confirm that the "Back wire" is a 3 core cable connected pin for pin? 3.5mm stereo jack plug to 2.5mm stereo jack plug.
I have just bought a second hand unit with the track wire and transformer but not the "Black wire" (Bachmanns description) hi
Thank you Derekr.

Bachmann are pretty quick to answer any questions users have, did you contact them at all?

No not yet, thought I would see if I could find the information first before bothering Bachmann.
