    Avionics boo boo. As I learned yesterday and likely might have a month or so ago had I remembered to run the OAT wire out of the LW root, there was no wire from the GEA24 for the fuel pressure sensor. I had mounted pressure sensor to the fire wall and hooked the wires for it to what I thought were the correct wires coming to it. The colors matched. The number did not. I hooked the fuel pressure sensor to the GDU25 with the same color wires as the 24. BAD!

    When I realized I had not installed the OAT, it made me double check. Well one of the errors was that there was no wire running out of the GEA24 and p243 for the pressure sensor. It was not built into the harness. You might imagine some frustration trying to get at that GEA24 also once the boot cowl is on too. Once I removed the connector, I could clearly see there were no female pins in the connector at 1,2 & 4. With extra OAT wire, I figured I would make a harness with that wire since they had same color wires. I just needed the female pins. Did I see those in a tote. Nope! I saw the whole harness all 6 of it with female pins on it and solder sleeves on it too. There is no call out for this that I remember but our revised manuals will have the correction. Peace to those who find the harness and remember this. Here are a few pics of connector P243 without the pins in it and a pic of the harness GEA35A22-3.
