Sorry - Pin 2 and Pin 19 on the GTX327.

Your recommended drawing has icarus output from the 5600 going to pin 19 on the transponder. Stein has wired the GTN650 output to pin 19 on the transponder, and his wiring schematic puts the AFS 5600 icarus output to Pin 2 on the transponder. I wanted to make sure these two inputs didn't conflict with each other
