Brief Description: Routed and connected ELT harness
Used Serial port1 to send GPS data to ELT transmitter. this was missing a ground wire so I had to take apart the power lead connectors of on of the other serial ports and attach a ground wire. Re-routed serial port 1 wiring behind instrument panel and ran harness through wire tube underneith fuselage floor. Cut hole in wall between cockpit and luggage compartment and installed ELT switch and activation alarm, then connected harness.
