With the big wires grommets properly ProSealed, I did a final check of the wiring and added some spiral wrap in spots where I thought chafing was a possibility -- primarily the com antenna at the firewall (that connector really should be a right angle connector) and also some of the wires to the HIC modules area that I thought might contact the frame of the transponder. I also tie-wrapped a couple of spots. Then I reinstalled the upper fuselage skin (of course I'm short two plastic washers and I have to order some of the stainless 507 screws in a future Van's order).

And then I attached the second G3X. That done, I followed the instructions, put a piece of tape on the upper right corner of the G3X, reinstalled the canopy frame and checked for interference. Yep, it rubbed on both sides. So I filed and filed until it BARELY closes and open without hiitting but there's no way that's not going to rub slightly once the canopy is on. But I was mindful of the admonishment not to file all the way through the tube of the frame. How much is that? I don't know and didn't want to find out so once I got it to clear, I resigned myself to the fact there'd be rub marks on the upper outer corners of the G3X's, which there are anyway because that tape didn't protect squat. Whatever.

Finally, I cut the pitot lines where they meet and connected them with the quick connect FLF00023. Seems to me where that come up from the tunnel could be a chafing point; not sure how to protect that.

The other thing I have to figure out is what to do with all the extra wire from the trim servo.

I have a ground power unit on the way so I don't wear down the battery when testing everything out, and I'm awaiting a Halotron fire extinguisher before I power everything up. The regular ABC fire extinguishers destroy electrical equipment and aluminum.

[Update 2/4] Needed, ordered, and received more AN507C832R8 screws and a couple of black washers for the upper fuselage skin and instrument panel. It's funny how hardware walks away after inventory.
