For those of us that still use a Backmann E-Z command.
I wanted a power wire that I could walk around the inside of my layout, so I made one. Bachmann wanted $5 + $4 shipping for a 41" lead. Bachmann's wire is something like a 28 ga. wire, so I beefed mine up some. I had plenty of 16 ga. wire and the stereo mini plug was cheap.
