Since late 1990 onwards till today, all car wiring cables has different ratings. Different amp and volts for those cables. Why? Save cost. They do not need to use same cable gauge that would cost more. And use cheaper gauge cables on some areas like lights. LED lights does not need to use high gauge rating cables so they use cheaper cables there.

The idea that all cables have same capability is not valid anymore. Just ask any car wiring shop if they could replace your modern car wiring with cables that they buy off shelf. It will not work.

Thats the price of continentals lor. If i were TS, i would fcuk the warranty, fix it and sell the car and buy a Potong. At least the expectations are much more lower.
