    So many CNC machines, and equipment where I retired from used tons of mil-spec Amphenol connectors which work good for multi-conductor cables. They have an endless choice of different configurations, with as many pins you want. They look like this style.

    Who wants a big screw together metal connector in their car for every connection? I'm not building an airplane or space capsule.

    AMASS has a variety of connectors used for drones and other electronics that need low resistance, continuous high amperage connections and are subject to vibrations. Might be worth a look to see if they have what you need, they're not expensive at all. Only downside I could see is that you don't crimp the pin you have to solder it, but they're very easy to solder. I paid $6 for a 5 pack of XT60 connectors, 60amp 500V rating. (If you go this route avoid knockoffs, they're not near as good and they're everywhere)

    I don't know but I think maybe gold-plated connectors are a little over-kill for what I'm doing. Plus I'm not seeing anything over 3 contacts per connector. They do look like a good quality connector, and not expensive. When I was an engineering manager for HP one of my responsibilities was reliability qualification of interconnects (ASIC, Memories, CPUs, and connectors) for our computers. There are literally tens of thousands of connections inside a high end server and they all need to work.

    No, your car will never fly, it was just another option for some connections, that are commonly used on many things that don't fly. And they look cool. They can be good for something in a cable anyway, since the wires don't have to be fanned out into a bigger connector.
    They take up less space, like I tried to do in school studying to be an astronaut.

    I use Molex connectors in aircraft interiors. They work great and provide positive connection. Great for interior use, i plan on using them on my 55.

    I always build my cars so that they will fly

    They would appear to be just as good as the original spade type connectors that GM used for years. GM used the spade type everywhere inside and under the chassis. The brass terminals lasted for years under crummy conditions. The fact was they were easy to clip off and replace terminals. But the copper wires often corroded and required replacement as well. Today’s insulated wires seem far better to complement the weather tight terminals available. But they are more costly than Molex or the spade connections.

    I’ve pulled apart some original 50’s & 60’s warped harness to find bad wiring as well as corroded terminals. Today heavier gauge wire complements better terminals for better safer longer lasting connections.
