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. https://tinyurl.com/jh4af75h https://tinyurl.com/j42nf3w2 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: https://tinyurl.com/2y845k35 >I often learn of new techniques here, and don't like >to miss out on safe, convenient alternatives. 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.
