Only ones that have been pirated are avalable.
Which is close to all of them… You just need contacts in low places 
Also I would not use the word “pirated”. These are not secret documents, with some inherent value or a purchase price. They are just restricted by the manufacturers, so that only dealers can get them, which is done to support the authorised dealers and to make it harder for freelance installers to do anything. It is IMHO a pure restrictive practice because an installer who can do the work legally but is not an authorised dealer (and the client is aware of possible warranty implications – this is by itself yet another restrictive practice which would IMHO be illegal in the EU) should be just fine to do the work.
Honeywell/BK gave up on their controlled circulation years ago and most of the manuals for their old stuff (which is almost all they make ) are online. Garmin are a lot tighter but a few years ago they had a big leak whereby google managed to index up their dealer website, and some people then wrote scripts to download the google links. So a lot of G500 and G1000 manuals escaped into the wild back then.
Having the RMI re-wired as we speak. Extracted VOR/LOC COMPOSITE OUT (#1004 pin 8) and ILS ENERGIZE (#P1004 pin 29) from the GTN-650.
Both connected over the RMI NAV1/NAV2 selection switch.
While measuring and cleaning up the wires from the RMI, we found a unused cable. Shielded with 2 wires. Measuring to the PINOUT we found these to be OBI COS LO (pin 7) and 26 VAC 400HZ (VOR HI) [Pin 32] on the KI-229.
Looking at the PINOUT from the previously installed KNS-81, I believe that it only needed ILS Energize + VOR Comp Out to run the RMI.
So why we now suddenly found this un-used cable is a mystery.
Any ideas?!
The KI229 needs only the composite for the VOR needle.
The ILS Energise is – I believe – used to park the VOR needle when an ILS frequency is selected on the NAV radio, to avoid confusing indications.
The 400Hz input is still required for the compass ring – as discussed earlier in the thread. Same applies to the XY inputs which determine the compass indication of the ring.
The ILS Energise is – I believe – used to park the VOR needle when an ILS frequency is selected on the NAV radio
How do you park the VOR needle on a DMI? Relative bearing 360°?
3 o’clock I think.
Peter is right on this one. The ils energize is a discrete signal which switches the CDI from VOR to LOC mode, depending on the frequency selected. The NAV receiver knows by the selected frequency and the frequency VOR / LOC/GS allocation wheter a selected frequency is a VOR frequency of a LOC frequency. Operation of VOR and LOC modes is completely different. Therefore an insturment which works on a composite signal requires information on how to process the received composite signal. The ils energize wires fulfills this task.
As the RMI does indicate to VOR / ADF only, it uses the ILS energize discrete to park itselfs in horizontal position when a localizer frequency is selected.
I have gone through most of the installation manuals for what was installed in the aircraft earlier and what is installed now, and I cannot find any need for the 2 wires I have found. They are not cut, but properly terminated with heat shrink.
Both the 26v 400hz (Vor Hi) pin 32, and OBI COS LO pin 7, are always marked as NC (I guess N-ot C-onnected).
And to run the KI-229 from the KI525, only these wires are needed:
So I guess I can just leave it as it is.
