I was thinking about this myself.. Since the yoke moves, maybe cut out a stick to proper length and use that to set to "takeoff" trim? I don't truck my trim indicator as well. Using that as a measuring device to set proper trim would prevent surprise nose up departures

It really sucks.. I loved my avionics guy on a personal level and he was a good friend. He just overcommitted and left a lot of planes grounded upon his passing. Now the KT76A, Alt Encoder and is all wired up! On this one, I just had one question. As stupid as it sounded, I would rather clarify if its not 100% clear to me..

Well, Its been a long journey. I installed my last panel with the help of an avionics guy. I put in a Garmin 420, KX 165, GMA 24, PS Intercom, Sandel 3308. Fast forward a few years later, I purchased a 430W, GMA345, GFC 500, 2 GI-275's to upgrade my panel. 5 Years ago, my avionics guy/Garmin dealer told me to strip everything out of the plane and we will work on it together and we will have it done in 2 weeks. If anyone knows the avionics guy in OB, he was notorious for stuff like this. 4 years later, he passed away. The guy that took over his shop, passed away 2 months after the fact. So my scenario is there are no avionics guys in KOLV, the shop in MS quoted me $25k to finish things up and we don't have that kind of money at the moment. Even if we did, we still couldn't ferry the plane to him with it being stripped down. The solution: I found a guy nearby that will mount the servos, inspect everything and sign off on my work. The plan is, get everything wired up, then the new avionics guy is going to inspect, then we will ferry to his shop. I am very confident with making wiring harnesses. This new avionics guy is doing me a favor and I don't want to bother him with questions. These guys are really busy and its takes a lot of focus to do what they do. The install will be legit, paperwork will be properly signed off and everything will be professionally configured and tested before I ferry the airplane. Here are some pics from my last install. I pinned every wire, and cut the panel myself. What I learned from last time is to make the harness longer, in case I want to add something later on, I can just pin it in the plane. And I am also using lacing for bundling

Thank you Eric! That's what I thought, but I would rather be safe than sorry! You will probably hear a lot of stupid questions from me as we go through the rest of the panel. If its not 100% clear to me, I am just not going to assume

Making significant progress on my wiring.. On Pin 60 on the 430 it says to pin to "common" on the altitude encoder. I do not see a "common" pin on the encoder. Where should I pin that?

In the GI-275 manual, Garmin has approved part numbers for the ethernet cable. I checked online trying to source it and either no one sells it, or its out of stock. I did find a a source after lots of searching: Part Number: ECS 392404 www.wiremasters.com I thought I would put this out there in case anyone needs it.

Yeah, that's the config I am going to go with... At least 2 have 2 vertical nav sources with that config.

Thank you!

Since I am installing 2 GI-275's, do I daisy chain them together with the 430, GMA, GMU 11 pins? I love Garmin install manuals, but dual install wiring is not clear.. Thank again for all of your help! I look forward to getting this bird back up in the air : )

I got the correct pins

Looks beautiful and capable

Both connectors purchased off of Ebay

One down, one to go!

I see what your saying, but according to this, I am going to pin an 18 gauge wire to 15, then I am going to splice that wire, connect my (looks like 4) shields and 18 guage wire to the ships ground. I think I like garmin manuals and install methods better. Like those 4 switched pins that have to be wired together, doesn't make any sense and it's not explained clearly in the manual. I am doing forensics and finally found an explanation of why those need to be pinned together. This is stuff that an old school avionics guy knows off of the top of his head and that wisdom needs to be passed along through tradition to us whipper snappers. Anyways, I know it looks stupid me asking questions and clarifying, but I just want it to pass the smoke test, so it's better to ask, than experiment. I was able to wire up that audio panel and 430 without any questions because the instructions are clear and the notations make sense too. Last time I installed this radio, I think we terminated the shields to the back plate of the tray. I wish my avionics guy was still alive. Off of memory, he could explain each pin, each configuration.

I think my avionics guy who is now deceased ordered them from mouser or digikey or something like that. It's when I try to pull it up by Bendix's part number nothing is pulling up since thar part number is so old.

I know how to make shields. I have done a panel install before. It doesn't make sense to pin to 15, which goes direct with separate wire to the ships ground. Ground them to the tray, that makes a little more sense, like how garmin terminates shields at the connector. Here is where I am at so far with the project. All those wires have heat shrinked wire splices for the shields. I just haven't put them on the connector yet or buttoned up the harness. I still have to pin the 165, 275s and GFC 500.

So pin it to 15, connect all the 16 shields to it, then terminate it to the ships ground? They are also shielded at the Garmin connector. I guess I will wire as illustrated, as everything is being done according to the manual, but that doesn't make any sense to me whatsoever. There has to be other ways to do this! Maybe these guys should engineer for BMW! As written, it would probably take 12 gauge wire and a ton of solder to terminate those shields, the lead from the solder alone would prevent it from conducting due to resistance. I al looking at the diagram right now and its making sense to me, except for grounding the shields to pin 15, then grounding to the ship.

I know these are universal parts with different part numbers, I just don't know what to order..

I have to go with what I have and the KX is almost perfect and has the digital display. It's almost new... Absolutely beautiful.... The 420 is much easier to install, but the KX gives me an ILS in case the 430 fails... I might have thought this out, but I'm a VFR pilot and don't know much. Just wanted others to chime in.. I have what I have and it's a big leap from the 170 where I had to tap on the vor or rub the harness underneath to get it to transmit..

I have both, which one would you install? I like KX 165 for backup ILS, but Garmin for install simplicity. Since a lot of you are instrument rated, which one would you install? From what I am seeing (not instrument rated yet), a lot of approaches are step down.Which one would you install? The 420 has no wass and no ILS. I know both are not what I should have in the plane, but I have to work with what I have.

Does anyone know where I can buy the connectors for this? I was able to find one under Bendix PN 030-1094-60 (36 pin) but I cant find the 030-1094-59 (30 pin) and no one sells install kits for these. Im sure its a common universal part, but dont know where to look. I just need the connectors, I already have the pins. Thank you guys!

Here is what I found on BeechTalk, So I am just going to leave those pins as is: Connect pins 11, 12, M, and N together. See the attached diagram. Internally the power goes through the on-off switch, out through pins 11 and M, then back into pins 12 and N. It still does make sense, but there was a reason I connected those pins together. Hope this helps..

It doesn't make any sense to ground the shields to pin 15, then ground to airplane. I have a dedicated ground bus bar. Should I just bundle those shields up and ground to the bus bar? Also, the switched power outs and ins 12,N,11,M are all tied (jumped) together, capped off in my current harness.. P901 11,12 has a resistor and are linked together. (I am pretty sure this is a Sandel item and I can remove) P401 pin J and 901 pin 5 are daisy chained together and I am not seeing any reference why in the sandel manual or KX manual. Once I get through these questions, I should be able to wire the Kx 165, I might have a couple questions on 275, but I think I got it

That's a lot of pins going to one ground pin. Should I combine them all using 18 Guage wire to pin 15. Thank you so much for your help!
