another interesting thing...
when you get your uglys... find the "INSULATION CHART"

compare that to the information stamped on wiring intended to be exposed to high temps, corrosives, flamable liquids, irregular installations, tightly bundled situations, below freezing, UV breakdown, continuous stress of heating up and cooling down etc...

thats why i mentioned a 10$ junk yard automotive wiring harness with useful color codes exceeds the application of a tube radio.
Best part is 90% of it is flex wiring.

nearly 100% of all the wiring in an automobile will have no information stamped on it,, and if it does,, its because the vendor / supplier just does it.,,not something the auto maker would ask for. The reason is auto makers and others are excempt from NEC compliance yet they are meeting a very stressful application using copper wires.
