Hardwire 55 ton Climax installation

[JoshatTonys]

Greetings,
I'm working on putting a Soundtraxx 090 sound decoder into my 2 truck climax. In order to make room for the speaker I had to pull out the existing board and plug assembly. Now can anybody tell me which wire (coming out of the tender bottom) goes where? They're all black so I don't have my usual color coding to fall back on.

Thanks.
Josh
