I have had a hard time finding the .110 inch female connectors to hook up to fastrack either in stores or on line. Then I found a train store near me that also has a car audio shop in it. Turns out the connectors for most car speakers are the same size. So I was able to pick up 20 connectors for $2.00. So if you need connectors for fastrack try your local car audio shop. Hope this helps someone.
