TrueTrak ADI has a built in GPS. Pin 6 is RS232 GPS out. Soldered blue/white wire from 3C shielded wire to ELT to solder cup on pin 6. Heat shrink for strain relief. Put VOM on to test circuit through the connector to ELT end ...all good.
Marked and dead ended 3 unused wires from AFS EFIS... blue wire, pin 34 for flaps not used as Vertical Power is controlling and displaying flaps. Two orange-XXXX wires unused as well....forget what they were for but marked in avionics manual if needed in future.
