Yes!  Thank you.  I found that thread just before I read your recommendation!  I guess the final word, after all the words were written, was... USE THE RED WIRE!  I did.  I'm happy!  Thanks again for the pointer!

I just purchased a Bachmann 5 amp power booster.  With great excitement I opened the box, and unpacked the contents.  Then everything came to a halt! 
What is the "factory suggested" method of actually connecting the booster to the track terminal strip?  The instructional video (and written text) simply say "connect it."  The booster package includes a raw wire, but neither a direct plug-in to the terminal strip, nor any kind of adaptor to the existing Command Center terminal wire? 
I gotta believe somebody has crossed this brdige before me!  Have I missed something?
