The APM 2.5 has one telemetry port, one GPS port.. there are other I/O ports but haven't used them.

So the cable will need to connect S3 from the extend board to the Telemetry port on APM.... and S2 on the extend board to the GPS Port on the APM.

Both ports have 5V supply.. so either one will be fine. (Xbee tends to use 3.3v which is supplied by the regulator on the Crius Extend board btw).
Is there a chart showing the pin out definitions for the APM2.5 telemetry and GPS ports?
