Some of the section of the KAI on the dual G3X display aren't particularly complete, especially if you have the extra-spendy silk-screened panels. In one section it tells you to countersink holes that don't need to be countersunk and in another is doesn't tell you to countersink holes that do need to be countersunk. So the only real way to identify the countersinking is to put the panel section on and put the G3X in and see which holes it's covering. Those are the ones that need to be countersunk. So I did that over a couple of days, bringing the panel home to do the task, and then I reinstalled it and test fit the G3X. I haven't yet permanently put it in because there's a few things I want to do before closing things up. Some wire wrap arrived from Aircraft Spruce that I'll use to protect some areas that I think might be chafe prone. SCREW pan HD 4-40 5/8 came in a Van's order along with some heat shrink. I also still need to install the autopilot control head. BTW, I've given up trying to fit the harness in those plastic doohickeys down near the fuses that Van's wanted installed. They're just not big enough and it's just a really, really crappy design there. I would much rather have put some Adel clamps in. I'll probably leave the plastic junk in and tie wrap it "closed" around the wires. That's another area where chafing concerns me because of the metal throttle and fuel shutoff cables that share some of the space. I may wrap some "rescue tape" around the wires. We'll see.
