Ok, long delay in this so sorry to anyone following the thread wondering if something useful from me would ever come out. The proper connector for programming the lightning head is
HR30-8P-12PC(71)
DigiKey Part Number HR586-ND
Manufacturer Hirose Electric Co Ltd
Manufacturer Product Number HR30-8P-12PC(71)
This seems to fit and work properly. *NOTE you need to order pins for the connector! I strongly suggest getting the PDF on the proper sequence of how it goes together its not super obvious and a royal pain in the ass to take apart.
The pin out for the lightning head is
Pin 1 KEYFILL (Data from whatever version of the KFD your using)
Pin 2 NC
Pin 3 Ground
Pin 4 NC
Pin 5 KEYLOAD (Wire to ground puts the radio into keyload mode)
Pin 6 BUSY (Used to program channels/etc nothing to do with Keyloading)
Pin 7 SWITCHED 12V *Power to run programmer boxes
Pin 8 PTT
Pin 9 RS-485M (Used to program channels/etc)
Pin 10 Mic Audio
Pin 11 Hanger
Pin 12 RS-485P (Used to program channels/etc)
If your wiring to one of the various KFDs they generally have Ground, Data and Sense. For the 5300 and Lightning head you only need Data and Ground. You don't need to do anything with Sense and can leave it float.
The connector for the 53xx series radio is
DigiKey Part Number HR1258-ND
Manufacturer Hirose Electric Co Ltd
Manufacturer Product Number RP13A-12PE-13SC(71)
Description CONN PLG HSG FMALE 13POS INLINE

The pin out for the (Normal 5300 or 53ES *Ver 6 with the Oval Speaker)
Pin 1 KEYFILL (Data from whatever version of the KFD your using)
Pin 2 RX-AUDIO
Pin 3 Ground
Pin 4 MIC4 *???
Pin 5 KEYLOAD (Wire to ground puts the radio into keyload mode)
Pin 6 MIC6 *???
Pin 7 BUSY (Used to program channels/etc nothing to do with Keyloading)
Pin 8 SWITCHED 12V *Power to run programmer boxes
Pin 9 PTT
Pin 10 RS-485M (Used to program channels/etc)

Personlly I hand crimp the lead from a 1/4 resistor to the pin, hand crimp and solder it so that it can fit into the connectors. Then I solder the cable wires to the clipped off resistor wire and heat shrink them. Both connectors are very tight fits and getting them in is almost as much trouble as extracting one.
Hopefully this will save people from buying the KVL premade up cables that typically cost more then the KFD keyloaders. Thanks to everyone who hung in there while I sussed this out. Will try to post something about the various KFD keyloaders and how to make them all work have gotten the Arduino Hat version, a Chinese made KFD mini from EBAY and the W3AXL KFD Micro all working. It seems that the issues are two fold. Getting the right Firmware (if needed to be loaded) into the device and using the latest KFDToolGui (Version 1.8.7 or newer) which works with all the KFD devices I've tried and on the Chinese made KFDMini finding the non standard 3.5 TRRS Phono Jack that is 17mm rather then the normal TRRS plug that is 15mmg tip to base. *Anyone with leads on how to obtain more of these weirdo 17mm TRRS jacks? And WHY someone would do this SIGH... Saw a video about these Chinese KFDMinis being all bad which I learned is not true but... Won't work with any connectors I can find. At least not without taking a normal 15mm plug and physically grinding them down 2mm. Which works but what a pain in the ass.
One last comment on the 53ES series versus the Lightning head. I can verify that if you pull the front panel off the 53ES you can swap directly in the front panel of a Lightning head and it seems to work fine.
