First round, I bought one. ![Shocked :o](https://www.bachmanntrains.com/home-usa/board/Smileys/default/shocked.gif)
For all the next ones, I've just been splicing in the necessary amount of similar guage wire.![Wink ;)](https://www.bachmanntrains.com/home-usa/board/Smileys/default/wink.gif)
But if you're not confident in your wiring or don't have the tools the extensions are the way to go.
Get a multisize wire stripper - the green wire is pretty thin.
Solder would be the preferred method.
