I didn't have much to finish up on the avionics harness tonight. The first wires I ran were the RS232 aviation data serial stream out of the Garmin 430W that go to the transponder (to automatically let it go from standby to active), to the EFIS, 406 Mhz ELT (for precise location in case it is activated), the TruTrak Autopilot and the trutrak ADI. I also needed to run another RS232 wire that goes from the EFIS to the 430W (for fuel information) and the 327 transponder (for altitude).

Next on the list were the ARINC connections that the EFIS needs for its HSI. There are three pairs of 2 conductor shielded wires that are needed to the Garmin 430W -- GPS IN, GPS OUT and NAV/ILS OUT.

The final wire I ran was the marker beacon antenna feed to the PS Engineering 7000B audio panel. It's time to put this puppy into the project and fire her up!
