SteinAir sent me the hardware necessary to install the connectors on the backs of the COM radio and transponder so I installed those. I had to order a long #1 tip screwdriver to finish the transponder though. I also made minor modifications to the wiring route so that wires aren't resting on the cooling fan. I added the GPS and XM Radio antenna and then I started on the AOA retrofit which is kinda rinky dink.

I drilled a hole in the wing and installed a rivet and then drove the mandrel out (mandrel broke on the first attempt but thy send two. Then I added plastic tubing and made a godawful mess with RTV trying to seal it in place. Not sure how to route the line going inboard. The instructions aren't very good and a drill template isn't to scale.
