Over the last 3 days, I pinned the d sub connector for the elt, wired and connected the panel switch for the elt. The pre-fab wire bundle was designed for a ACK elt, which utilizes ships power. I blindly added a breaker for this because it was in the interconnect drawing, but it turns out the Artex elt doesn't use external power, so I capped and stowed the power wire and will likely use that breaker position for something else.

Finished the panel switches & pulled wires to appropriate locations. Wasn't happy with the fuse link I had fabricated for the pitot heat annunciator discrete input. specifically, it was a 18 awg wire with a 22 awg link and the 18 is too big to fit in a sub D pin for the GAD27 connector. Ended up redoing this with a 1 amp inline glass fuse.

finally was able to solder the co-pilot PTT. It's a good thing these switches from Stein are cheap. I melted 2 of them trying to solder wires on before I got the hang of it. I was trying to heat the terminal tab and wick solder toward it, but that didn't work at all. much better result when you heat the wire and tab at the same time from the top and wick solder on it from the same area. FYI- the nut on the front side of the PTT is effing metric. 10mm.

Started wiring up the CO detector today and ran into a couple of problems. The wiring diagram shows a pin that's already in use for something else on the PFD.

Called Levi to see if there was a solution, and he told me I could just wire it into the MFD and it would work just as well. During that conversation, we discovered that there was a pin in the wrong position on the PFD connector. Specifically it was in position 36 but it was supposed to be in position 37. I unpinned and relocated per his instruction.

Tomorrow I will finish wiring the CO detector and it's entirely possible I will get far enough along to put power on this thing!
