The signal from the Fastrack switch is a low-current bi-polar signal. The signals under discussion take far more current and voltage to operate. The issue is, turning the low voltage, low current Fastrack indicator signal into something you can use.
My method would probably be a couple of resistors, a transistor, and a signal relay. Now I have a set of isolated contacts that I can drive anything I desire from.
There are some Arduino compatible relays available on eBay for very cheap prices. They are TTL compatible inputs, I may dig one of those out and see if the Fastrack switches will trigger them. If so, that would be a nice turnkey solution to the issue.
