Thanks for taking time to look into this. It may work, though it is looking like
I'll need an avionics shop with old manuals to derive an actual pin out from
the King radio to the Narco indicator. Seems like they use different names for
probably the same signals. Oh well, it be easier to just source a KI206!

You folks done good. To recap for any relatively
new members of the List, I'll re-iterate the
three pillars of longevity and performance
in made up conductor joints:
GAS TIGHTNESS between conductive elements of
the power pathway. This is best achieved with
PRESSURE that exceeds the compressive strength
of the joined materials. Thus two materials
become essentially one thus excluding the
primary threats to joint integrity - moisture
and oxygen. This would the 'wire grip' in
PIDG style crimp.
MECHANICAL support of materials subject to
cracking under vibration at the stress risers.
I.e. the transition from stranded to solid at
the ends/edges of the gas-tight interface.
This would be the 'insulation-grip' on a PIDG
style terminal.

PROTECTION FROM THE ENVIRONMENT calls for
mitigating threats from environmental
effects of water, salt, corrosive gasses,
solvents, etc. Examples of this are
illustrated with incorporation of various
sealing techniques where called for in
the most stressful environs.
It's always good to be skeptical of new
processes until the details are sorted
and confirmed. Poor information is often
delivered with good intentions. Here's
an article that appeared in Sport Aviation
a few years back:

I've exploited the convenience of the WAGO
style connectors (of which there are many
examples out there). But only on relatively
low current house and appliance wiring.
Lighting branches, ceiling fans, etc. but
never where there's a risk of moisture/condensation
ingress.
That same spring-barb, high-pressure
connection has been around for decades.
First recall seeing it in strip-n-poke
termination on wall receptacles and switches.
In years since, I think I've seen the same
technology on other small wiring components.
It's noteworthy that the entry hole in
receptacles will only permit termination of
14awg wire . . . 12AWG wire won't go in.
>Thanks again for the input, all.
Thank YOU for asking and taking the time to
digest and understand. Share your knowledge
at every opportunity.
