I do not agree: in the rEvodreams the wires are protected from degradation!!!

tric is the following: normally you don't solder when clamping molex connectors, but we do..

goes as follows: make sure you have a clable that melts nicely by the heat of the fluid solder, without degrading the plastic: cut to length, put solder on the wire and keep the heat a bit on the wire: solder enters in the wire and melts the plastic a bit round the soldered part. stop heating, solder solidifies and cable is sealed by the plastic.
now for clamping the molex: on the connector, you have 2 clamping zones: make sure one clamps on the plastic wire, the other on the soldered wire,
then, to give extra protection for the connector, put grease on it (oxygen compatible of course :-) and slide it in the plastic molex.

of course, you can not do that on a degraded cable: not possible to put solder on it :-(

That is a nice touch, certainly, and is a great idea. Very surprised to find it on mine!

The reason I refer the coax idea is that soldering may, possibly, add a failure point to the cable and fluid could still get past the solder if there is any airspace between the strands by capillary action. The coax connection would completely seal the wire without additional connections.

Don't get me wrong, your method is much more robust than the connections I have in my Inspo and a vast improvement.
