I had this debate with my bud, he uses the stock 12v plug in the back of his JLUR for his fridge and I use the ARB wiring kit. He thinks I am crazy and I think he is crazy. The ARB wiring kit was $21 and installed in about 20 minutes. The ARB plug screws into the ARB 12v plug so it never comes loose. That to me is worth the $21 dollars all by its self.
