Just purchased and received a Williams Diesel True Blast II Sound Unit. Purchased it new from Bachmann parts , but they sent no instructions. Do I need them? There 's only a red/black pair of wires and I suppose I can just connect it to a convenient track voltage point inside the engine, but is that all there is to it?

Yes that's all there is to it!
Red to the rollers and black to the outside rail or the frame.
Did the T.B. 2 unit come with a 2 wire plug? Or did it come with just 2 wires? Usually they just plug-in to the circuit board. Or you can wire it like ROYBOY mentioned. To activate the whistle you will need to push the whistle button and it will play the grade crossing sequence(2 long, 1 short, 1 long), the bell is activated by the bell button on the transformer. If your transformer don't have both horn & bell features you can use a Lionel sound activation button sold separately and wire it in reverse for the bell. Or you can add a double pole double throw switch between the transformer and the track and reverse the track power to the track to get both the whistle and the bell feature.

Got it working without the instructions. Then Bachmann sent me a sheet that was supposed to come with it.
