Luckily mine hasn't had any major wiring issues yet lol well the only major one I had recently was that my positive battery terminal would get corroded enough to break the circuit and my car would just shut off completely when I tried starting it. I cleaned the crap out of both cables and terminals and it would corrode just enough to do the same thing months later. I got new cables from the auto parts store; of course, the new cables are 1 positive and 1 negative and the stock cables has like 1 positive that splits off into 3 and the 1 negative splits into 2.
